I was going to try the $20 trick at the Mirage for a tower suite but my sister is going to be there for 1 or 2 of my 4 nights. Seems they only have king beds. If the sofa pulls out that would be ideal. I live on the East coast she on the West. She doesn't gamble and is not fond of Vegas (she must be adopted) so I would hate to ask her to meet me and make her (or me) sleep on a crappy roll away or the floor! Thanks in advance for the info.
