Oh, Uzbekistan, you really are one of my favorites. Cheap hotels and food, reasonable transport, and amazing cities that makes me want to linger. If you could just get that visa hassle fixed, you’d be rich on the coffers of stunned travelers from around the world.
The only thing here that really needs describing, I think, is the visa. For Americans this is expensive no matter what at $120 for a single-entry visa with normal processing times. My application was rejected the first time, though, so I had to apply twice. Since the second was going to be outside of the country (in Vienna, as an aside, where I got the visa in about 30 minutes!) I had to apply for a Letter of Invitation, and then pay the $120 app fee AGAIN. For a total of almost $400, especially adding the overnight shipping to return my passport after the first try so I could leave the country the next day.
For the rest of the country, cheap cheap cheap. Even single rooms in hotels with wifi are rarely more than $15. For a dorm, more like $6 or $7. Food can be expensive, but it never has to be. Plov, shashlyk, and beer every day for less than the cost of a lunch back home.
Go here, enjoy it, and save money. Just make sure to get your visa on the first try.
