We are a family of 4 - my wife and I, our 12 yr. old son, and his grandmother. This was our 5th but first non-Disney cruise. We therefore found ourselves constantly comparing RCL to Disney and are happy to report that RCL compared favorably.
Pluses:
1. Barcelona port - we arrived 10:45 am Saturday and were onboard by 11 - well laid out embarkation area and not crowded at this early time. Much better than our Sept. 2011 experience with Disney at Port Canaveral.
1400 - large, quiet and very private stateroom that felt like a suite. Huge balcony. Slept 4 comfortably.
