The official policy is still double occupancy. However, every class for at least the last month has not been assigned a roommate.
This may be because of some people not showing up for the class. However, NO ONE in the last four classes has a roommate. How long that will continue is anyone's guess.
I've heard stories from people who had to double-bunk last year that it's possible to bribe/sweettalk the hotel desk staff to get a single room also.
The HomesteadSweetHomestead is not great, but it's okay. It's in a VERY unsafe neighborhood by the airport. The hotel has beefed up security so the rash of car breakins/thefts in the hotel lot seems to have abated.
