We were at Branson Nantucket in early September over Labor Day weekend. . They are currently building a row of about 5 buildings lower on the hill from the completed units. LOTS of construction going on. Those buildings are fully framed; they are also working on starting additional units down at the street level. THAT construction is just starting.
Check-in is done at the sales center on Hwy 265. From there it's at least a mile to the actual resort. They close at 5PM. Not sure how you're supposed to check-in if you arrive later in the evening. Luckily, our guests arrived before 5PM and got the info on how to get into our unit (lockbox outside the front door with the keys). Even though they gave us very specific info on how to get to the unit, it just looks like one big construction site from the road - we drove by it several times - my wife saying no way this was the timeshare..really hard to find this place AND your unit after dark.
The unit was nicer than many timeshares we've stayed at but had quite a few construction defects (and the building must have been at least a year old so they had plenty of time to fix the problems), really cheap towels, etc., and our unit happened to be infested with fleas. I get huge welts from flea bites and my legs were covered with them.
