You are on the Orlando forum which is for non-Disney hotels.
If you are interested in Disney Value resorts then I would post in the Disney Resorts forum for all info on their resorts.
But if you are, Disney no longer provides any rollaways for values. You can bring your own blow up mattress if you have two folks who don't want to sleep together. The new rooms at POP will no longer fit another mattress if you plan to use the murphy bed. AllStars Sports, Music and most Movies rooms (getting renovation) in addition to AoA Little Mermaid rooms will fit. If you need more sleeping surfaces you can look at the ASMusic Suites, they are still a reasonable option with more bedding.
If you are talking a non-Disney hotel, which ones are you looking at?
