Now we all know that every time you ask a question, you are subject to a different answer, but I called MS's about this very issue before our trip last May. My question was could we use the Community Center if we were staying at BCV? I was put on hold while they checked for an answer, and when she came back, she said that we should feel free to head over there whenever we desired.
We were never questioned about it during our stay, and when I was speaking with one of the CMs, she said that they see members who are staying at BCVs on a fairly regular basis. This is just my experience, YMMV.
