We stayed at the Bahia Principe Coba from 8/13/14 to 8/18/14 with our 2 boys, ages 6 & 9. We really don't have a single complaint about the resort. :) Due to plane cancellations we arrived a day late and were able to check right in since our room was already ready. No problems with the desk people or other any other service people. Paid $100 extra for a non-stop transport from the airport, took about 1 hr 30 min. and included non-stop return which was only about an hour and 10 minutes.. fast driver? ;) Resort is very close to Xel-ha and other excursions so once you're down there, you don't have to spend a lot of time in vans from there on.
Room: We stayed in a 3rd floor room in building 22 which overlooked one of the pools. We were given a 2 double bed, 1 single bed room. The beds are very firm, which is perfect for kids and I. Husband's back suffered a little, but still less than he has experienced with other hotels. After reading a lot of reviews about poor AC, we were pleasantly suprised to find the air in our room worked great- it was always nice and cool at all ours of the day and night. We kept the ceiling fan on to help. We did notice the fridge only seemed to work sporadically, so water and drinks were not ice cold, but it wasn't a big deal. The room and bathroom were spotless and in great condition. The jetted tub worked great and was really relaxing. The 3rd floor was a litlte bit of a hike, but it helped offset all the buffet meals. :P We saw no bugs or reptiles in our room during our stay. Once at night there was a racoon lingering around the bottom floor but it ran away. There is a little ravine/grove outside the building where a large coati family lived, every morning we saw the babies running around. Snack bar is right next door, and the large dinner buffet wasn't too far. We were short walking distance to the waterpark, and didn't have to hear all of the noise associated with it. ;) Saturday night there was some sort of party in the pool with loud music, but it didn't last too late.
Complex: it's huge. We needed a map with us at all times the first 3-4 days. But there are trams running every 3-5 minutes so it wasn't a big turn off. Everything was very clean and well-groomed. Tram drivers are polite and don't expect tips. If one did do something special like wait for us when they were about to take off, or vary their route slightly to get us closer to our destination, we did tip them.
Beaches: the nice thing about the size of the resort was that there were several types of beaches. One near the Akumal hotel had some docks and many many fish swimming around you while you swam. People snorkeled here. The beach by the Tulum was a little rockier, and had seaweed flotillas near the shore. There are large, long sandbags put out to break the large sea waves to make it more comfortable/safe to swim. Our boys found that little crabs liked to hang out on those, especially in the seams, and so this quickly became their favorite beach. They spent hours on the bags catching little crabs (which were pincher-less, so not a danger) and bringing them back to shore to show us. We consistantly found loungers just past the preium member area, and there was a snack bar/bar right near there as well so it was a good place to be. Never saw a person in the premium area, all those empty chairs and curtained beds sure looked nice tho. We didn't see a lot of the other beaches since this was their favorite, but our last night there we walked the beach from the Tulum to Coba areas, and went by where they had sea turtle eggs roped off. People were on loungers here at night, maybe hoping to catch a hatch?
Food: was good. We aren't gourmet eaters, so we didn't didn't experiment much with the menu. That's not to say there weren't good options- everything from burgers/fries to many seafood choices. We and the kids were always able to leave full and happy. Breakfast in the Coba was great, good bacon, french toast and pancakes, and the oldest was able to get am omlette every morning. We ate at the Portofino- excellant filet mignon! Our dinner at the Tequila wasn't so greaty- very slow service and the food wasn't that great when it did finally come. Our last dinner was at La Tortuga, the brazilian place. Our 9 year old was brave and did the meat sword thing with us, and he and we liked almost all of it. Other nights they ordered from the kids menu, and even tho they aren't big on fish, they liked the fish fingers a lot. One had the grilled chicken one night and that was good too, as was the spaghetti. Kids enjoyed endless ice cream cones during our stay and liked the swim-up bars where they discovered they love shirley temples and virgin strawberry daquiris.
Pools- yes, they were warm, it was in the 80s and very sunny/humid all week so it's what we expected. Certainly didn't stop us from swimming and having a good time. Boys climbed on waterpark our first day there, thought it was good but weren't "all about it". Had just as much fun swimming around in teh regular pools and going to the swim-up bars. One day were joined a water balloon fight in the pool closest to our building, and one day we did volleyball at the large pool next to the waterpark. It was pretty hard to find 2 empty loungers at that pool- we took 2 chairs from the snack bar and sat in them for about half hour til we saw someone leave and were able to get their seats. There were also areas on the grass you could lay on. Sea was warm but still refreshing. Workers were gathering seaweed from the Tuilum beach. Note- it's not the gross slimy seaweed, it's clumps of foilage that float. They don't stick and aren't slimy. :) Could always find a chair there if you walked a little ways.
Summary- had a great time, great resort. Boys are already asking when we can go back. :D
