Many rooms at the Disney hotels have 2 queens and a day bed that you can request (not guaranteed since they are assigned 1st come, 1st serve). Or there are some nice suites in nearby hotels (ex. HOJOs) that have a King, bunk beds, and a pull out couch.
We stayed at Embassy Suites South this summer. We requested one bed, but you can get rooms with two beds. And every room has a hide away bed in the "livingroom". There are even two tvs. Embassy Suites are nice because you get the bedroom and livingroom giving you a little more room to spread out. It is a mile from DLR but has ART pickup.
We are staying at La Quinta Inn in their 3 room King suite. It has 1 King, 2 doubles and a pullout sofa bed. It has some nice perk it has 2 bathrooms, 2 tvs. We are paying a little over $500 but are splitting the cost with 2 other people. We are staying Oct 10-15. Can't wait
