40 classes availabe for use through May to end of August. No holds or extentions. You can use your classes spread out over the 4 months (2x/week) or you can use them all in one month if you wish! Classes will expire on August 31st. Great for people who have busier schedules this summer as how you utilize your 40 classes is flexible and up to you! Works out to only $12.5/class! A summer steal!
