Thanks guys. Actually, I should have said that we finally, after much research and comparative shopping, booked HAL Statendam. We were about to do Princess, but HAL worked better and for some reason, Princess had a hold on cabins?? We didn't want to wait around and wind up settling for something we didn't want - or worse, not be able to book. Would obviously have preferred Mariner, but moneywise, pre-cruise wise, HAL fit. I'm told if we went for the upgrade, we wouldn't know what it was until the VERY last minute -also, this is for '07.
Marc - I didn't think of obstructed vision as being an "upgrade," but glad you brought it to my attention. I think I'll probably follow my TA's advice and stay put. Mid ship - deck 7 or 8 (Veranda deck), I can't remember but, it's a pretty good location. Thanks again!
