Details: 3-4 weeks for this trip in July/August (not quite sure just how much time I can take off yet), without stopovers it would be 2 nights from Amsterdam to Moscow, then 6 nights going on the Trans-Mongolian, then 2 nights to account for one night in Moscow to catch the next day's train and a night in Beijing before catching the plane home (I'm using the info on Seat 61 here, if it doesn't sound right let me know). So 10 days at the very minimum just for traveling, BUT it would be rather stupid to go all that way without stopping over, and the ones that sound interesting to me are Minsk, Moscow for more than a night, Irkutsk, Mongolia (the capital doesn't interest me so much as something out on the steppes)... was in Beijing last year for a week so probably no more than a night or two there, and while I'd like to stop in Poland I realize realistically I'm already going to be dead tired from this trip, so better to save it for later. Anyone got some advice on these stops?
So I figure the above is tight-but-doable if I can get 3 weeks, though obviously 4 would make things better, but I know it's not a part of the world known for being easy to travel around so I'll defer to others on if it's a viable itinerary for the given time.
Other things I'm thinking about-
1) I have passports for both the USA and Hungary, and because the visa fees are jacked up in most of the countries listed above for Americans I'll probably be using both (as it looks like Mongolia bucks the trend and doesn't require a visa for Americans but does for Hungarians). So does anyone know whether said countries in question would care about whether I was using a different passport to enter the next country down the line? (ie upon entering China would they wonder where my Mongolian stamp was if it was in a different passport) Or do any of these borders do immigration in one go instead of having a no man's land between them?
2) I'll be seeing if any friends want to come along but, well, if none of them do that's never stopped me from my adventures.
I'm sorta thinking the latter would be true in July/August because it'd be the height of the touristy season, but wanting to check and see if I'm being a complete Pollyanna or some such.
3) Weird question perhaps, but I'm wondering about the cleanliness on these trains after several days on them. This is because thus far the most epic train journey I did was the 48 hours to Lhasa from mainland China, and towards the end of it things got rather disgusting even by Chinese standards. I like to know what I'm getting myself into...
Thanks for the help guys!
