Buddy pass, bring guess on certain days

You have a extra ticket for a friend

That on certain days you can bring a friend for free.

You should check the membership portal for more accurate information. Summer days May 28-31, June 2 or 3-7.

There are days in the summer where you can take a free friend. Other days you can for a discount. And it's 1 per membership, not per family. So if there are 4 of you with memberships, you can take 4 friends. But it's only on designated days each month.
