A guest card is issued to each household and each card allows for 50 guests per year. A Guest is defined as anyone five years of age and up who does not have a Sienna Member ID card. Guests must be escorted by a Member ID Card/ Guest Pass Card Holder. Members are responsible for the behavior of their guests, and must remain at the pool with their guests at all times. Guest attendance guidelines per family/per visit are as follows: Residents age 21 years and older may bring in up to 5 guests at one time (specific teen/young adult guest guidelines below). Guest cards are issued from the SPRAI office during office hours, 8 a.m. - 7 p.m., Monday - Friday, 10 a.m. - 4 p.m., Saturday (May only).
