My top Great Wolf Lodge packing list tip is that on the day you check-in, you are able to access the facilities at 1pm. But your room may not be ready until 4pm. If your swimming bag is handy, you can change and enjoy the pool before your room is ready! On the day you leave, do the same thing. Checkout is at 11, but you can use the pool and facilities until the end of the day! They also offer an option to purchase late checkout. We use these wet bags to keep our swim stuff from getting everything else wet.
