I’m travelling through Phon Penh next year; staying for a couple of days on my way to Ho Chi Minh.

Any ideas on the best; most economical way to get there? Ideally I want to avoid the airlines as there are quite pricey, but I’m on a tight schedule and would need to get there within a day. Is there a river boat or a bus service? Are they are good?
