After MGM Springfield was approved by Massachusetts gaming officials to extend alcohol serving hours on the casino floor, Connecticut casinos also seek to keep the bar open later.

"We believe with New York, New Jersey and now Massachusetts having that option, we will need to raise the issues associated with Connecticut leadership at the appropriate time," Chuck Bunnell, chief of staff for external and governmental affairs for the Mohegan Tribe, said in a statement.

Both the Mohegan Tribe, which operates Mohegan Sun, and the Mashantucket Pequot Tribal Nation, owner of Foxwoods, seek to extend liquor service hours on their casino floors.

The request has been proposed several times over the years, a spokesperson for the Mashantucket Pequot tribe said. "Now that MGM has extended their hours in Massachusetts, it only makes sense for us at minimum to do the same, if not implement even longer service hours, and do so responsibly."

The Massachusetts Gaming Commission voted in June to approve two hours of extended alcohol service for MGM Springfield, allowing drinks to be served on the gaming floor until 4 a.m.

Drinks will be served in different cups between 2 and 4 a.m. and only available to customers actively engaged in gaming. Restaurants and bars not connected to the casino floor will still close at 2 a.m. and alcohol sales will be prohibited between 4 and 8 a.m. daily.

The $960 million resort casino will open in downtown Springfield on Aug. 24, offering gaming, entertainment and dining.

MGM's 125,000-square-foot gaming floor will feature 2,550 slot machines, 120 gaming tables, a poker room and a high-limit VIP gaming space.

MGM will partner with venues downtown including the MassMutual Center and Symphony Hall to host shows and performances. Other entertainment offerings include an eight-screen movie theater, a 10-lane bowling center, an 8,000-square-foot pool and a golf simulation facility.

There will be several food and dining spaces, including a steak house, Italian restaurant and a sports bar.

The casino's license extension will be reviewed 90 days after opening and be amended if needed.

The Connecticut tribes are opening a joint venture just south of the Massachusetts state line. The $300 million casino project in East Windsor is scheduled to open as early as the spring of 2020.

Casino officials say the project will feature 60 table games and about 2,000 slot machines, as well as a few restaurants, bars and retail operations. It is expected to offer about 2,000 parking spaces.
