Prices in Myanmar have doubled or tripled this year for hotels. I listed the prices for rooms in the daily heading. I paid $45/night for a single at the MayShan hotel in Yangon (for reference, Lonely Planet from 2011 says a single was $20!). Rooms were pretty basic, mine had no windows but had aircon, TV, free wifi (though painfully slow) and breakfast included. The bathroom was basic too, just a single room containing a sink, toilet and shower hose. It would be a 1* hotel anywhere else probably. Location was great though. I booked directly via email from their website but they are also on agoda.com. I had to book several months out as hotel availability is tight to booked solid now during high season.

The Aung Mingalar hotel in Bagan, I booked by sending a message via their facebook page. $28/night for a single. Very dark room with odd wood panels on the walls. Had aircon (but wasn't very effective), wifi (but didn't work) and breakfast included. It was clean and they provide towels. I've stayed in worse places. It's also bookable on booking.com

The RGN-NYU(Bagan)-RGN roundtrip was $240. I booked it through the MayShan hotel and paid cash when I arrived.
