I would love to explore both Texas and AZ, but in consideration of our personal situation (mom in nursing home) I think the best place for our first winter is Florida. We are currently exploring options in the Fort Myers area (easy to hop a flight back to NY). I know it will be more expensive, we can afford it for our first winter, but certainly not every winter! I'm thinking we can explore other parks from there as others have suggested and "learn along the way" what our preferences are. I plan to make some calls to parks tomorrow and find out if we can reserve for 2021-22. I'll let you know!
