The transition has been eased in other ways. Most islanders have moved in with relatives, and many have no plans to return home, Puerto Rican leaders said.

“If I have to start from zero from somewhere, then I would rather do it here than in Puerto Rico,” said Yasmeli Santiago, 28, one of the sisters-in-law who moved in with Ms. Garcia last week.

But as days and weeks of living with relatives slide into months, frustration over privacy and food costs could easily escalate. Ms. Garcia, who works nights as a cashier at a hotel and moved here three months ago from Boston, will have eight relatives, including a baby, living with her and her three children in a two-bedroom apartment.

Before her relatives arrived, Ms. Garcia, who bought their plane tickets, figured out the living arrangements. She gave up her bed so the two couples could trade off sleeping in her room. The children all pile onto a foldout bed and two bunk beds. The rest, including her, sleep on air mattresses in the living room.

The women will share cooking duties, and while food stamps have been slow in coming, the family has picked up groceries at food pantries. Finding jobs is a priority. Fortunately, the job market is relatively healthy in the Orlando area, where the unemployment rate is 3.2 percent, compared with 4.1 percent in the country over all.

“I am ready for this,” Ms. Garcia said of the jumble of people in her home. “I think we are O.K.”

Others are not as fortunate as Ms. Garcia’s relatives. More than 1,100 Puerto Ricans were staying in Florida hotels as of Nov. 14. But with peak tourist season fast approaching — Orlando gets 68 million visitors a year — rates are climbing, and the new arrivals will soon have to find more permanent places to stay.
