I'm still debating on whether to go with Princess or RCL.
I have a deposit on the Golden Princess in a Visa Suite and a deposit on the Vision of the Seas in an Owners Suite. This is for Christmas this year going to Mexico.
I like the fact that Vision's OS is very large at 520 sq. ft. But, the VS on Golden is an aft cabin.
Also, the price is about the same with RCL being $60 more.
