I have a reservation at BCV for 9/16-9/25. However, at 7 months, I'd like to split the stay with the VGF (which I've never stayed at) from 9/13-9/16, which means that I'd have to drop 1 night from BCV. On the 13th, should I reserve all 4 days (will the system allow me to "modify"-just drop one day from BCV?) Or should I just add 9/13-9/15 at VGF, then on the 16th modify BCV (hopefully) to VGF. I'm so scared about dropping the 16th at BCV, because I don't want to end up without a room for one night.
