love advice

have only 14 days and we are flying in/out of zurich. want to spend 3 days in vienna and plan to visit prague and budapest. traveling by train...after vienna does it make more sense to go to prague first or budapest??

There are direct sleeping cars from Zurich to all 3 towns. So Zurich - Prague - Budapest - Vienna - Zurich could make sense.
