I hope you don't expect DVC quality at the beach. I've never stayed in one at St Pete beach, but the beach timeshares tend to be more rustic, just like a lot of the older/smaller beach hotels. No problem for me because I'm more concerned about location than fancy, but just wanted to bring that up.
Timeshares are the only way my family is willing to travel now because of the space and amenities.
