Rosemary,
I feel your pain but I also know how difficult it is for them to schedule rooms for people’s needs.
A few years ago there was a couple there with the same problem and they drove to the pool from unit one. To many this might sound like over-kill but if the problem is yours, you’ll understand the need.
We’ve been so very lucky in that we’ve only stayed at the pool end but we also book more than a year in advance and tend to be moderately flexible in our days.
Beyond those few problems I hope you enjoy BSV as much as we do. I don’t think it’s a place for everyone, particularly if a cloistered resort atmosphere is your thing, but for an independent traveler we think it’s THE BEST. Enjoy your remaining time.
