Yes. You can buy tickets for just Lego Land, or you can buy tickets for Lego Land and the new Lego Land water park both located in Florida. Lego Land is about 45 minutes away from Tampa Florida. For additional info, click on the link in the related links section.
It really depends. I would have to say own. The cost of real estate in Florida is getting to be as high or higher than California. If you buy land now, it will only increase in value. I know from experience.
