Hi Dana - lots of us on the Moms Panel go on "girls' vacations" together also. Seeing Walt Disney World with your friends is one of the best ways to enjoy the resort!
Club level is wonderful, and if you think you'll take advantage of the amenities, it's worth it. It really depends on your budget for the trip. I think there are other things, like the park hopper option, that's a better value for your money, so if you have to forgo other things to afford club level, it's probably not worth it. Keep in mind you'll also want to do some shopping while you are there!
To see everything with your friends, I highly recommend getting the park hopper. Hopping around to multiple parks in one day is the best way to see as much as possible. This past weekend, several of the Moms Panelists traveled to Walt Disney World together for a long weekend and we visited up to three parks a day!
Before you leave, talk with your friends about the "must-dos" at each park. If you have a smart phone with Verizon, the new
Mobile Magic application is a good way to check out wait times so you can optimize your time. If you don't have Verizon but do have an iPhone, I have found that the WDW Lines app from TouringPlans can also be accurate.
Remember to save some time for more relaxing activities, like hanging out by the pool!
Have a great vacation!
