The point requirement really depends on where you're working. The whole time I was in the CP, the CP staff really stressed that it was no more than 5 points to meet transfer guidelines. This is true for a majority of the roles, however for entertainment (Performers, Photopass) it's actually 4 points or less, so make sure you check with your manager, I almost missed out!
To do the 150 hours it's going to be tough, but if you lump in the hours all together, you can get a short term rental while you're down there. You will DEFINITELY make friends there who will either stay on for PT work, or who already live down there, and so you can couch surf is you play your cards right! I have several friends who have said I can crash with them when the time comes. It's easier to go seasonal if you have your managers do the paperwork before you leave, rather than wait. And let me just say, it is SOOOO depressing when you leave. You seriously go through Disney with drawls, so just save yourself the pain and do it before you leave

Also, I live in California and to me, it's definitely worth it to stay seasonal for Florida! I LOVED my job and it would be my dream to work there full time
