We've done many VR including our own 50th anniversary party. We were able to pre-book VR for a full compliment of guests, other times we spoke to the Head Sommelier to tell him we were interested in a VR dinner, and when he had 12/14 he would arrange it. In my memory he may have had one date and as time went on and interested parties requested, he may have added another date. The wines on our party were at and charged at our level of interest, the group, or unaffiliated (for loss of a better term) were at Crytal's choice at a fixed price for all, no upgrading or downgrading.
