Idea is good, execution is bad
If you don't have enough money - travel with Bontour. If you can - fly planes, relax on cruise ships. The bus is the last century, crowded, uncomfortable, night journeys, 500-700 km journeys almost every day. The toilet works, but you can't use it, it's absurd. Household stops are rare, when already urine hits the head, then the guide makes a stop. Summary: not kamilfo, bad, but not very budget.
