Quoting t_maia
I am sorry to be so blunt, but geographically and economically it makes no sense to combine Slovenia with Ukraine and Russia. It would make a lot more sense to combine Slovakia with the 2 countries, especially when you travel with friends or family.
You do not write where you are based, but if you are from the UK there are very cheap flights to Bratislava. From Bratislava it is then possible to use the City-Star Ticket to travel around Ukraine and Russia by train.
You should also consider to extend your trip timewise, Russia and the Ukraine are huge countries with lots of things to see and do. If I was travelling by train in these countries and was using City Star Ticket, I would plan on having at least 6 weeks.
I'm from Massachusetts.
To be blunt as well, my friend and I have no desire to visit Slovakia
. We didn't just close our eyes and point at a map and land on Slovenia. We picked it out because we both want to visit it, and I've heard a lot of great reviews. We hope to go back in a few years and hit Croatia/Bosnia/Albania/etc... But, for now, we've selected those three. We talked about taking a train over to Zagreb and spend two nights there, but we're already visiting three countries, so we're set for now.
Our plan is to fly to Ljubljana, then fly from Ljubljana over to Kiev (It would've taken forever by train). From Kiev, we're flying up to St. Petersburg. The train would be about half the price, but I've been deciding most things on this trip, and my friend didn't want to be stuck on a train for 24 hours, so she chose to fly. From St. P, we're taking the train down to Moscow, and then flying home.
We've already cut some things off from our trip due to expenses (Downgraded on hotels, we don't know if we can make Chernobyl', and some other things, too). In fact, we would've had to have cut off a week if my cousin wasn't letting us stay with her in Moscow, because lodging there is so expensive.
Yalta looks beautiful, and I'd like to go there someday. It's not a terrible trip, it's an over-night train, but we're only spending five days in Kiev, so I don't want to have to use three days for one place we didn't plan on.
Novgorod, too looks great, but also a trip. I checked through a train stations, and it's 8 hours, which is too long, even if it IS roundtrip. I would've killed to go over to Lake Baikal, but a plane is too expensive, and the train takes too long.
I agree, I wish that we could extend our trip, because if we did, we would've visited both Yalta and Novgorod, but my friend can't get so much time from work, and I actually have to be back for a late-may event. We also simply don't have the amount of money. When we're spending around $70 a night for a hotel, at minimum, even split, is a lot. I'm a student and even though I'll be working full time come late January, I still have to afford plane tickets, eurovision tickets, hotel expenses, spending money, which adds up in excess of $3000, not to mention little things here and there. Maybe I'll hit the lottery soon, and I can take a year-long trip throughout Europe... :-P
