1) Is 1 May celebrated in Ukraine at all - are shops and attractions open? If it is celebrated, what happens?
2) I would be really grateful for an explanation on how I can go about getting a Ukrainian prepaid Sim card for my mobile? What is a good place to by it, what documentation would I need to show, and what, roughly should it cost? Any idea whether international calls can be made from prepaid SIMs? (believe it or not, I have never used prepaid SIMs, I've always had a subscription, so I don't know about this in English either... ) This conversation is well over the level of my skills in Russian, so it's important that I know exactly what to ask for..
3) What maps can be used online for checking addresses in Ukraine? Google maps confuses things with bizarre transliterations etc, and it does not seem to be reliable outside the EU.
4) Is it not needed to use a credit card when BOOKING a hotel in Ukraine? I have never personally booked a hotel without using a credit card and I do not feel confident that my booking is valid, since I was not asked for it....? I booked online and ticked that I would use "money" (meaning, cash, I guess) to pay for the room, and just clicked submit. There was no field for entering credit card details.
