I had the following complaints about Royal Caribbean:
1. not much to do on the ship - too small. No boardwalk either!
2. Spa folks messed up my billing many times - there were multiple cancellations and recharges for three items! It was confusing to me as to why they did this - I asked and did not get an explanation.
Had a leaky shower tube in the bathroom which was not fixed during the entire cruise even after I brought this to their attention.
