First, I recommend that you bring some of your older towels if possible. If they're like ours, they're not as fluffy and don't take up as much room. If they should get taken, it won't be any big loss (none of ours have ever been stolen). We also bring ours from home because it makes it easier to spot our chairs with colorful towels in a sea of white towels. And if someone should accidently or on purpose take your rented towel, they will not replace it, you will have to rent again.
