Pennsbury also had a showcase for top academic players.
If you do plan an East Coast Ivy trip, do not limit yourself to just Ivies. I would also suggest for high academic schools:
1) for Div 1 I would suggest the Patriot League(ie Lafayette, Lehigh, Bucknell, Colgate...)
2) DIII NESCAC (Amherst, Tufts, Williams, Bowdoin.....) or NEWMAC(MIT, WPI, Babson...)-disclaimer my DD went to Babson
