We were at the Playador/EC in February. It's has all the necessities. They were doing some construction when we were there, but should be finished by now. Also by now the restaurant should be open. The staff is very nice, although not very knowledgable about AC, or the mainland. The pool is above ground, but very clean and refreshing.The bar there is the Crazy Canuck, and Don and Carol are wonderful! Try their Mango Tango's!
The dive crew there is great! Oliver is very layed back, and extremely knowledgable. If Felix is out with you, watch him play with the sharks, they are like his little puppies. We also did the cave-tubing trip with them to the mainland. Wild day!!!
Make sure you have breakfast at Woody's (across the street). The grocery store is just a quick trip.
Have a great time! We did, so much that we bought a house on AC, and will be down in May to close!
PS: Everyone is very serious about no shoes, and only taking 1/2 the clothes you think you'll need.
