We've got the 7-day Bounce Ticket for Colonial Williamsburg and BGW, purchased through BGW. I've got an email with barcodes that I realize are "not our tickets," but vouchers to be redeemed for tickets. I'm trying to decide whether to start the trip at CW or at BGW, and one of the questions is whether one of them can "redeem" the tickets in a way that will work for the other. If I go to CW first, can I get my BGW tickets activated and skip a visit to the BGW ticketing window? Or vice versa?
