How about doing some activity where she gets a load of exercise right before you leave? Hopefully she would be tired enough to sleep afterwards.....also, you could give her some sort of brain or time-intensive treat, like a bully stick or a kong toy filled with treats. An article of clothing that you have worn placed in her bed might help her to feel less anxious. Oh, and leave the TV on where she can see it in the hotel room! Hope this helps......
Congrats on your son's graduation!
