We just returned from BWV and we had a 2-br; the pull-out couch in the 1-br was the old kind--but in the studio, it was the newer kind where you just pull on the strap. I thought ALL the sofabeds had been updated??
It was my understanding that they replaced all the sleeper sofas at BWV and BCV about 1.5 years ago. They were the type where the cushions are not removable and flip underneath to help support the foot of the bed when it is opened up.
Maybe they had a problem with the sleeper sofa and had to use a replacement.
