We just spent a very nice week at Pacifica Sands in Xtapa. The staff was great. The beach was wonderful and lots of comfortable places to sit by the beach or around the pool.
The resort buildings are built into the mountains but they have transportation from all the buildings right down to the beach if walking is a problem. The place has a very tropical feel to it and has a small area with exotic birds and animals. Every afternoon they feed the crocodiles. The food is plentiful but okay. You never get food as good as a private restaurant when all inclusive which this was. The ai fee was not exorbitant and when you pay in advance they give you an extra dinner at their best restaurant and a message at the spa. In all I would not hesitate to return.
