The beach in front of 1100 is a bit wider and nicer than 1300. 1200 has a big palapa out next to the water further away from the buildings. Overkill imo if there are only two of you. 1300 had a decent beach when we left at the end of June and is next to Pizza per Tutti. Rooms 1313 or 1309 have a palapa directly outside the room. When we were there in June, you had to snag it by 7:30. a.m. One day dh went out at 7 a.m. and the one in front of our room was already taken. First come first served. We usually make our request through LisaN@megaresorts.com. Someone on another forum stated last week that the email address was no longer working. In that case I believe you can contact email@example.com
I hope this helps. If you have any other questions, please let me know.
You cannot get one at the Tam. I know they will heat bottles for you at the buffet, but the buffet is not open 24 hours.
Imo, bring a "travel size" one from home. The only other thing I can think of is to purchase a small coffeemaker at one of the supermarkets when you arrive. You can use it to make hot water and then heat the bottle that way.
