We were in the same situation you are when we first started looking for warm winter weather. First year we went to Florida and traveled the entire State. Loved the Keys. Florida is beautiful. We never stayed in one location longer than two weeks that winter. The problem we found is that the State is such a narrow strip of property it was just too crowded for our comfort zone. They cannot handle the influx of winter visitors on top of the already overcrowded highways/ businesses. We felt the locals were more than a little annoyed having to deal with so many winter visitors.
The next two winters were spent in Arizona. Arizona is beautiful! We made a base camp in Surprise but again we ventured out and tried to cover most of the state. With side trips to Vegas and Southern California. So much to do and see in Arizona!!
Then we went to South Texas. The Rio Grande Valley. I think it is fair to say there is not a lot of beauty in the land in that area. Just pretty flat. Of course South Padre Island is beautiful. What we found were the people so kind and welcoming. They genuinely liked us and were very kind and polite. Yes I realize we are quite a boost to their economy but we are to Florida and Arizona also. You do not see the big "Welcome Back Signs" all over Florida and Arizona as you see in Texas.
You just have to venture out until you find the place that is the right fit for you. Even in the RGV it took a few years for us to find the location and the park that felt like home to us. I can't remember how many years we have been coming to the same park maybe about 8 years.
A lot of the fun and adventure in RV'ing is exploring all the options.
