Its been a quite a while but this is how I remember it.
The first bldgs built at Star Island (Star Island I and II) included non lockout true 3 bedroom units. I believe these were the 3 story buildings very close to the clubhouse and south of it and possibly some of the 3 story ones to the west of the clubhouse right around the lake but can't remember)
The units developed by Vacation Break at Star Island and later on were the 2 bedroom plus den with sleeper sofa lockout type units that have a full kitchen in the side B and a mini kitchenete in the den in side A (the smaller side). Some of the VBR developed units were the smaller 3 story buildings (earlier ones) with the 6 story buildings being built later on (by VBR or whoever). As far as I know all the 6 story bldgs are the 2 bedroom plus den lockout type and were built later on (after they stopped building the 3 story bldgs).
The difference between the true 3 bedroom and 2 bedroom plus den is that the third bedroom in the true 3 bedroom has an actual bed (a queen?) where as the lockout has a sleeper sofa and mini kitchenete. Plus the lockout has a lockout door given you some more flexibility even when using both A&B sides.
I think the true 3 bedroom units are under the STR code but you would need to verify this with the resort as I'm not sure if they continued to use VBR for all further units or switched back to STR (possibly phase III and on ????)
