When it comes to overwater bungalows anywhere near the Caribbean, the pattern lately has been to announce them long before they are ready to break ground. That wouldn't be so bad if not for the fact that years seem to go by and ground is never broken. Getting funding AND government approval for construction at the same time has been a major challenge, but not for the project we recently learned about.
Evidently there had been rumors in 2013 that Disney would be adding up to 20 overwater bungalows to its Disney's Polynesian Resort complex in Lake Buena Vista (near Orlando) as part of a major 2-year renovation. Now we have actual videos from May, 2014 of these things mostly built in the Seven Seas Lagoon that the resort sits on.
