Well they aren't that close, #1 is Purdue (Indiana) the other is Florida.. so not sure how that would be in air flight times.
Both have given me schedules for the weekend, and it seems #1 is mainly doing their activities on Friday, whereas on Saturday all that is scheduled is "depart campus"
Then school #2 is only having a "grad student party" on Friday night, and their activities do not start until Saturday, this is why I was hoping it would be possible to go to both- I will have to check how long the flight is between the two cities
