Hi! I'm still new to Tauck (only 1 river cruise). We are interested in a 2027 Treasures of the Aegean but the dates we prefer are already booked. I was told there are no waitlists but from what I've read, that isn't necessarily true. If I can get on a waitlist, do they work? Only a few dates are sold out but given my work schedule, we'd have to push off the trip by 4 months. We were also told that if we book our trip, we can't transfer dates, is this also true? Trying to figure out what to do so we don't miss out!
