We are also on the full VIKING B2B. Since the online system was not working, I sent in our shore excursion requests by Fax. When I read that some folks who were on single segments of this cruise were able to book online, I too got worried that the single segment cruisers were going to get all the excursion spaces and we, the folks who are on the longer booking, would be left high and dry!
Well, I was even willing to pay in advance to ensure we got our choices, so had my TA call Regent to see if we could give them our credit card and prepay for the excursions. The Regent agent said "NO, that was not allowed"! WHAT!?!?

I'm with you Margo - I am SO frustrated - I would almost be tempted to cancel altogether, but we have really been looking forward to the cruise.

I sure hope Regent has the good sense to do something to appease it's past loyal clients like all of us. They definitely have some bridges to mend here.
