We used the DVD player to put our 4 year old to bed every night..... All 3 of us in the pullout. LOL.
We found that the return policy, at 10:00 a.m. was too early for us (I know, don't even mention Early Entry, but with the time zone change and such, we just don't make it).
So this time I'm going to bring 1 or 2 with us.... She falls asleep anyway after 30 minutes, and doesn't mind watching the same one over and over.....
Otherwise, maybe you could rent some and bring them with you, or use Netflix with the mailers.
Just some ideas....
