For the cost of this property, there's very little that my husband and I had to complain about-- but I wanted to give a very indepth review for anyone who's planning to stay.
1. Facilities- this is an older property & there is maintenance that could be done. For example, big cracks and dark spots on the ceiling in the room areas that are clearly from water damage. The buffets have worn tiles, crumbling areas around the bottom of the stations, and overall everything is just 'older'. That being said, we didn't have any concerns about structural integrity and for the most part everything was clean and maintained.
2. Staff- The staff were very nice and helpful. Overall if this is your first time in Mexico, just get used to the fact that everyone you meet is trying to sell you something. You don't have to buy into it, we certainly didn't. This isn't unique to the Grand Princess/Grand Sunset.
3, Food/Drinks- We are admittedly 'foodies' and really found everything to be just 'ok'. Hot food wasn't as hot as I'd like and the cold food were usually lukewarm. Sometimes there were things (like their tortilla chips, fr example) that were stale. However, there was always something good and the speciality dining experiences were all very good. We enjoyed the Miso Thai, La Hacienda, La Vaqueria, Le Fleur, and Mamma Mia. Our favorite was Le Fleur and Miso Thai. These are dinner only places and were included in the package. Don't drink the water and I'd stay away from their frozen drinks.
