We're visiting Chandler in July and would like to do a girls day out for mom, daughters, and granddaughters. We were thinking at least part of the day would be going to the spa. Grandkids range in age from 6-15. While 15 year-old could spend the whole day getting pampered the 6 year old's probably going to poop out after a manicure or pedicure, so we're thinking short dayspa visit - not the whole day - followed by a nice lunch. Where would you recommend for spa, lunch, or other activities that fit girls day out theme?
