For the first 75 people who reserve a spot, the spa at the Ritz will offer a free happy hour Halloween event, which will include complimentary mini-margaritas, guacamole, gelato, chair massages, make-up consultations, trick-or-treat bags with spa and salon samples, and a 25 percent discount on retail purchases and treatments booked during the evening. We’ve been to these Ritz spa events before, and we’ve told you we love them. They’re worth your while for an hour or two during the week. Thursday, Oct. 29 at 7 pm. Ritz-Carlton Spa.
