We stayed in the LM rooms this past November and the beds were fine. We had 2 adults and 6 year old and a 10 month old. I believe the beds are the same size as the other Value Resorts.
The room was great and so cute. My 6 year old DD loved it!!! My only complaint was the room was very warm. You could only adjust the air to a certain temperture, but I learned from some friends that you can call the front desk and they will send maintenance to adjust it for you.
The resort itself was wonderful. We really enjoyed walking around and looking at everything!
Hope you all have a great time!!!
