When I was 45, I did briefly consider making the switch
I was there over Presidents Day weekend. The first day I went in (around 3pm) there was zero wait. The second day I went (around 10am), I had to wait 10 minutes. All the booths seemed open. I didn't find this matched up with my experience at all.
I can’t tell if my friends are convinced or if they’re too polite (or disinterested) to argue.
Soo. $5.4B - $10
