I'm a little confused by your questions. Blancaneaux and Crystal Paradise are two totally different experiences, especially in price. Most people who are thinking of one probably wouldn't consider the other. Both are very good choices but in quite different categories.
In Placencia, Kitty's does have three cabanas and it does have local character, but it is a (small) resort, not a house ... although Kitty manages a few houses in Placencia for the owners.
