Spring Break Trip Dates

After getting a lot of good feedback and considering airfare costs, I have decided on a compromise. We will be flying out on the evening of Thursday, March 21st (exact time still to be determined).  We will be returning on Saturday, March 30th.  However, to save us money on the airfare, we will not be returning to Philadelphia until approximately 11:30 pm. I hope that this is a compromise that will work for everyone. Thanks.
