The Tranquillity Membership typically comes with a pre-defined number of spa treatments or credits, which can be redeemed over the membership period. While there are no strict restrictions on the frequency of visits, the treatments are subject to availability, and advance booking is recommended. Some special services may require additional credits. You can explore custom membership options available at Tattva Spa for unlimited spa access. The spa membership can be redeemed by a single person on a day.
