An alternative to Mexico is The Dominican Republic, DR. All advertised prices for the all inclusives tend to have a 50% premium for single travelers. Least expensive DR tends to be Punta Cana. It is on the atlantic side. Water on the carribean side is a little warmer and calmer. Atlantic waves are still small unless there is some weather driving them. Try snorkeling 1/4 mile from hotel, look for snorklers that are spearing fish, this will lead you to the right place. They speak German as second language to Spanish so english isn't really functional. Keep this in mind if you are not comfortable drawing pictures and working out a request. Most visitors wer European so the beaches were a little more topless than mexico. No matter where you go tropical, if mold affects you negatively, stick with bigger name hotels, the smaller ones are older and prone to having some fungus in the air. If you have room problems anywhere, try asking nicely for another room, and maybe grease the guys palm lightly. Oh and the latest thing I have done to check out a resort is to look at it on Google or mapquest satellite photos, you can get the general location from the resort address and then key in on the resort with the right swimming pool shape. This will let you see the actual beach and adjacent area so if you want to be next to town, you can see how far it is, etc. Stay close to the resort staff if you have any safety concerns, they have guards and one actually walked my companion to the beach and back one night.
