Overall, we had a nice time at the Hilton Cancun Mar Caribe. However, I want to leave an honest review for couples/adults who are thinking of choosing this hotel. We booked this through Air Canada Vacations, and were pleased when we arrived as the grounds of the hotel are gorgeous (beautifully designed and clean) and the rooms (clean and modern). However, as an adult, this hotel lacks activity and features to allow for a fun trip. I've summarized below. Rooms: all room types are great - all have an ocean view and are modern. even rooms with small juliette balconies are lovely. Dining: buffet was good but would have preferred a more diverse offering of staple foods like rice, grilled chicken, etc. Steakhouse (a la carte) was our favourite, delicious food. You have to book a la cartes on their online website and can only book 2 days in advance. Availability was not optimal. Snack bar was supposedly open 24/7, but there was sometimes no attendants to serve you, and the food was minimal (pre-made sandwiches, etc.). Breakfast buffet was my favourite, but there was always a long line in the morning to be seated by the host. We never used the room service, so cannot comment on that. There was a pool buffet area as well, that offered hamburgers/pizza/ some buffet items during the day, which was convenient to grab something quick to eat. Clientele: being Canadian, we chose to travel after March Break (when the schools are out for spring break) on purpose, but did not realize Spring Break in some states was happening the week we stayed in Cancun. There were many teenagers, and many kids, not many young adults (besides the parents of these children). I cannot speak to the clientele/vibe of the hotel at other points in the year, but we would not return to a family hotel during Spring Break again. Bars: alcohol was varied and the drinks were good. However, the lobby bar closed down at 11pm each night (which was not advertised), so there was no entertainment/anywhere to go for adults who wanted to enjoy their evenings/have a cocktail. This hotel would benefit from having an adults only lounge/bar, or a disco for adults (not teens), that stayed open until 12:30/1am (like many other resorts we have stayed at). Entertainment: the staff was lovely and there was always something planned for the daytime. The night entertainment sometimes started at 8pm, and ended by 10/10:30pm each night. Again, nothing planned for adults. The resort was targeted fully towards/to entertain children. In my opinion, entertainment should be for both sets of clientele, as a family resort with guests of all ages. Beach: beautiful sand and blue ocean. always somewhere to sit (however, the chairs under the umbrellas were sparse and hard to reserve). the waves were very intense, given the location of this hotel/beach, and is not suitable for young children and/or older adults. I've heard the ocean is more calm on the other side of the hotel zone (closer to the top/around the bend). Pools: pools were nice and spacious, there was an adults only section with infinity/whirlpools that allowed for a nice reprieve from all the children and crowds on the resort. Spa: spa was small, but nice. prices were quite high for the small facility/lack of facilities. Again, a beautiful resort, but I would only return if I had a family with small children.
