If you get premium you'll also have to pay a $39 fee. It's one time only. So here's how it works: You sign up for premium, they only charge you $1 for that month. Next month will be $21 and the month after will be $39. Then back to $21 As a black member (the premium membership name) I get to use everything in the spa, bring a guest, but don't let them get you with the "Use all of our gyms". Yes, you can, but you can only use a gym other than your home gym 10 times a month. You will have to pick one home location. Regulars are stuck in one gym. Trust me, it doesn't sound bad, but I moved and really couldn't go to my home gym anymore. I wanted to switch, but even us black members have to wait three months to transfer. Some gyms are cool and will force transfer you, but others will make you stay the full three months or if they do transfer they'll charge you annual fee again.
It's by month. Base price is $10 for a regular membership. $21 for premium. A premium member can invite you as a guest for free, though.
I'm not sure the cost for a day. I joined years ago and I have a fee of $15 a month.
