2 months in florida or south ga

For the warmer temps you have to be below Tampa/Orlando. Above that you can see temps in the upper 30's sometimes worse depending on how aggressive a cold front is. We have stayed at Rock Crusher Canyon and it's very nice with a nice pool and club house and it has spacious sites. Crystal River is a nice little town that basically revolves around fishing and the Manatees.
I've also been in south Georgia when the temps have been mid 20's in January.

I am not sure the Canadians will be coming down to FL this year so you might try calling a few resorts and inquire about openings. Be prepared to pay big bucks.
