We are booked for the whole Easter week at BCV's. I called with another question to MS a week later after booking, and the BCV's were all booked for Easter week, with an exception of maybe one studio for a couple days. Hey, it can't hurt to try, but didn't want to get your hopes up, good luck.
Yes, it will be difficult but you should call to find out if there is any availability as it sounds like you will be requesting high point weekend nights that are more likely to be open than others. Only other warning has to do with whether you have been at that time of year. If not, understand that you should expect huge, huge crowds.
