Quite a while ago, prepaid in advance a King room ... thinking it was just going to be my wife and I. Turns out our teenage daughter is going to be coming along for this leg of the trip.

I haven't stayed at LeM Etoile, it lists rollaway beds, so I'm hoping worst case scenario (I'm platinum) that we're not rotating on the floor

Seriously, how concerned should I be? It's 4 nights pre-paid in Aug, and assuming the hotel were to allow a change to the pre-paid res, I'm gonna get spanked on rate at this point.
