Agreed on the guest fees! I'm in my 5th year of membership, buying the 10-visit plan, and a few times when I was with my husband and had gone through 10 visits, we decided it was not worth $50 to pay for the 2 of us for whatever short time we were going to be there. (Fee has now gone up to $28 per person.)
Do a Search on PriorityPass- there are plenty of discussions on it- but I've been a very happy customer.
