Weddings and receptions
Weddings are sold in-house, with customizable packages that can include venue rental, catering, bar service, furniture, linens and a dance floor. The site states that celebrations range from fewer than 50 guests to several hundred. Ceremonies can take place in St. Francis Chapel, known for its seven Tiffany windows, in St. Cecilia Chapel, or in the courtyards. The Atrio, the courtyard outside the chapel, is listed for 100 at banquet rounds and up to 408 in theater rows. Receptions usually move to The Grand or the Spanish Art Gallery, a 2,800-square-foot hall built in 1914 with a marble staircase, which takes 130 at rounds.
The team also hosts rehearsal dinners, bridal showers, welcome receptions and post-wedding brunches, as well as birthdays, anniversaries and holiday parties.
