Affordability becomes an issue
It does. For one 7 night cruise on the Oasis in June, 2010, I can do two 7 night cruises at the same time on other ships and in better cabins. The pricing for Oasis really troubles me. $4300 for the three of us in a standard inside cabin. I can't get over that one. People might say "but look at all the new stuff on that ship!" But we all know that most of that new stuff will have extra-fees attached to it and most of it won't be included in the cruise fare.
Granted there will be adjustments to the Oasis pricing as time goes on and they get a handle on the bookings and popularity of the ship. We'll see.
