The ONLY difference between Basic and Premium is hours of access.
Both memberships include the same amenities, the only difference is hours of access.
Basic access is:
Monday - Thursday: 8A to 8P
Friday: 8A to 4P
Saturday: 8A to Noon
Premium access is: 24/7/365
*Basic access does NOT include Sunday.
*Basic access has holiday "blackouts" (no access) that usually includes a day or two before and after the holiday in addition to the holiday.
*Basic access is computer controlled so it is very specific in regards to time - even one second early or late will matter in whether access is granted or denied.
