We have booked a great deal for a balcony on Celebration, then along comes an even better deal for a balcony on the Regal Princess. We have a couple days until final payment for Celebration. We have never been on the Excel class of Carnival ships. The Princess cruise comes out to $300 less pp, with potentially even more savings over Carnival if we choose plus. But we can't decide! Is cruising on the new class of ship worth the extra $$$?
