I am anew member at SSR. Just booked trip for Feb. at SSR, a 2BR and a studio. we have 6 adults and six kids. At the 7 month mark am going to try and switch resorts . Dont know where yet,hopefully a 3BR at OKW but not getting my hopes up. We will most likely stay with 2BR and studio. My question is how comfortable are the sleeper sofas? We will be staying 7 nights and I know some sofa beds are killers on the back. Thanks for the input.
