Can we tour two colleges in one day?

Short answer: Yes, if they're under 30 minutes apart and the tours don't overlap. Duke and UNC Chapel Hill (11 minutes apart) and Emory and Georgia Tech (9 minutes apart) are the classic same-day pairs; Harvard and MIT (4 minutes apart) are walkable.

Two campuses per day is the realistic ceiling for a parent and a teenager — three burns out both and blurs the comparison.

Always book the morning tour first; afternoon slots are easier to move if the morning runs long.
