I don't think it would be fun on public transport, its ~3 hours each way on the train/bus from Eindhoven. It is~1hr 45 in the car if car hire is an option. I was going to say never use Green Motion car hire in Eindhoven as they are worst company I have ever dealt with and are not even based near the airport. Thankfully for everyone they appear to have gone bust.
Personally I'd put the money you'd spend on car hire/bus towards Amsterdam flights or have an Efteling/Toverland trip instead
If you do go to Eindhoven I'd heartily recommend watching a VIP film in the Eindhoven Pathe cinema. They have a VIP area that includes a mega buffet with champagne before the film and unlimited nachos, popcorn or sweets to take in.
