I travel with mine on long trips with doggy beds, toys, blankies, collapsable food bowls etc. We stay at pet friendly hotels to not put burden on any family that may not possibly want pets as guests and to conserve our friendship lol
I also take disposable potty pads, harness and leash etc. If you can, and have room a crate to contain if you must leave her alone and she will get into something.
Leave with plenty of spare time for what ifs and to provide plenty of potty stops. Its no different than traveling with small kids.
Have fun!!
