Organizers of the inaugural Rocket Mortgage Classic golf tournament say corporate hospitality sales for the June PGA Tour event at the Detroit Golf Club are pacing far ahead of their expectations.

"We've seen unprecedented interest demand in tickets, hospitality and sponsorship," said Jason Langwell, the tournament's executive director and executive vice president for Chicago-based Intersport that's running the tournament on behalf of title sponsor Quicken Loans Inc. that owns the Rocket Mortgage app.

Langwell said hospitality inventory is 80 percent sold out.

Based on what Langwell said has been sold for the June 25-30 tournament, companies have paid about $2.6 million just for hospitality, which is multiseat or table structures such as chalets, skyboxes, and club space to be erected along the historic golf course's fairways, tee boxes and greens. That doesn't include hundreds of thousands of dollars in remaining inventory, or the millions of dollars in ticket sales and corporate sales of naming rights during the event.

Organizers increased hospitality offerings three times to meet demand, Langwell said, and even tweaked up prices. The inventory and pricing were created by seeing what could be built around the golf course, especially the final holes that are most in demand, he said. Intersport built the business plan, including pricing, around what 10 similar tournaments in the event's market-size peer group have done recently.

"Pricing is based off a comparison of what has been the right price point in other like-size markets, and also taking a look at various products in the market," Langwell said. "That demand has been so solid suggests we've appropriately priced the product."

The names of the companies that are buying naming rights and hospitality inventory won't be disclosed for about another month, Langwell said, and will coincide with the public ticket sale. Between 250 to 300 companies typically are involved financially in some way with a PGA Tour event, he said.

Companies spend large sums on golf hospitality for a variety of reasons, including branding locally on-site and via the national TV broadcast; as a reward perk for employees; and as a way to woo clients and generate new business via network during the week of golf.

At the upper end of Rocket Mortgage Classic's hospitality inventory are six "fairway suites" on the 18th hole that each seat up to 50 people each. Each suite is $120,000 and five of the six have been sold, Langwell said. The original plan called for just four such suites until demand necessitated adding two more.

"It's a great problem to have," he said.

The final hole also will have double-decker "skybox suites." The six upper-level boxes, which are for up to 35 people, are sold out at $90,000 each, while five of the slightly smaller lower-level boxes, which seat 25 people at $65,000 for the week, are sold, Langwell said.

The 18th also will have up to four of what Langwell calls "partner suites" that are only for companies that sign high-end multi-year deals for naming rights, hospitality, etc., and are not being sold a la carte, Langwell said. Two of the 1,200-square-foot suites, for up to 50 people, are planned now, and access will include the golf course's permanent clubhouse.

Quicken/Rocket Mortgage will have its own space wrapping around the rear of the 18th green, Langwell said. That's part of its naming rights deal.

The 17th green will have eight 25-person skyboxes that total a combined 5,000 square feet. They sell for $60,000 each and seven of the eight have been sold, Langwell said.

Twenty-person 20-by-20 open-air cabanas will be constructed along the entire left side of the 15th hole, and Langwell likened them to poolside cabanas in Miami or Las Vegas. He said all of them have been sold at $40,000 each. There are another 20 cabanas, slightly smaller and priced at $30,000 each, along the 17th, he added, and 14 have been sold. The cabanas include food and beverage service.

There are other options for companies that don't want to spend in the upper tiers of hospitality during the event. For example, behind the 15th green will be a "cool club, for socializing and fun" for up to 2,000 people with access sold in packages of two, five and 10 tickets, Langwell said. Prices range from $1,750 to $9,100 but access doesn't include food and drinks. Langwell called it a "massive structure" with nice views of the green.

"It's selling out," he said. "It's a more economical option."

Michelob Ultra holds the naming rights for the 15th-hole club as a national PGA Tour sponsor, but financials details haven't been disclosed.

At the 14th hole, a 10,000-square-foot club structure is being constructed to serve 800 to 1,000 people a day with food, beverages, and indoor and outdoor seating, Langwell said. Admission to the club will be sold as a four-day ticket for groups of two, five or 10. Prices start at $3,000 for two paired tickets to $20,000 for a table of 10.

"It's a great way to take care of a client or prospect," Langwell said.

A club on the 16th hole, which also will have views of the tees on the 17th, will be available for an $85 ticket that's basically an upgraded tournament ground pass for a day, Langwell said. That space will be for up to 2,000 people and will have a food menu and bar service for individual purchase, a patio with umbrella tables, and a covered viewing deck, he added.

The pro-am on the Wednesday before the tournament officially starts still has spots available for $10,000 individually or $40,000 for a foursome. Langwell said those who buy into the pro-am will be paired with one PGA Tour player on the first nine holes, and a different player on the back nine.

"It's selling really well," he said.
