Your reservations should always show up in the MY RESERVATIONS section of the website and MY TRIPS section of the IconGO app after you purchase (future reservations will be under UPCOMING, and you can view completed reservations under PAST). If they’re not there, it is likely that you are not logged in to the account that purchased the reservation or were not logged into an account when the reservation was made.
Note that for all reservations, email confirmations are automatically generated. Even if they do not show up in your account, you will still be able to redeem your reservation or coupon at the facility with your email confirmation.
