Why not create a National Girlfriends' Getaway Day? First, define what getaway means to you. Make sure it's a mental escape, not just a trip down the street for a mani/pedi, cutting straight to happy hour or pool crashing.
Did you know you can actually book a day room at many three- to five-star hotels? Check in first thing in the morning and clear out by the end of the day, and get access to all the leisure facilities. Sip umbrella cocktails by the pool, read trashy books and magazines and be super girlie—trade hair and makeup tips, and play truth or dare.
