I go to Florida about 1.5 times a year. About 17 nights. I don't have kids but may at some unseen point. I do have a niece and nephew so probably another solid 7 year of visits before they want different trips. I do visit DLR often and could use DVC points in the GCH but usually plan at too short of notice to use them.
A house would be an investment too, but at the bloated price may not appreciate greatly over time.
What would you do if you were me?
