Be sure to bring anything in her crib from home (pillow, blanket, sleep sack, stuffed animal) so that 1) you create a familiar environment to her even though you're in a different place and 2) she can associate the pack 'n play with sleep and not only play. This makes a big difference. Don't know what your sleeping arrangements will be, but we have found hotel rooms to be very difficult, in general, in getting our kids to nap and go to bed for the night because we are still in the room. It's always much better when we stay in a condo and it's more like putting them to bed at home, where we can leave the room and close the door. Best of luck!
