I was on the Christmas 2017 Allure of the Seas cruise. My wife and I had a balcony room. We have done about a dozen cruises, the last several on Royal Caribbean. As a matter of fact, this was our second time on Allure.
There were a few good things about the cruise. But, there were several things I really found disappointing.
The Positive
The room was nice - it had a balcony. However, the bathroom smelled like the bathroom of an old gas station.
Getting on and off the ship was SO easy. We drove and parked right next to the terminal.
Nothing really to see in San Juan.
