Booking travel: what websites should I use to get the best deals on flights and hotels?

Well, it really depends on the destination you're planning to go, but I can tell you that when I was planning a trip to South America, Ecuador to do list by voyagers.travel helped me a lot, so I'll leave a link for you o the platform that I use to find the best expeditions and get the most out of the trips.

I have a problem with choosing the destinations and places to visit, can you recommend any websites for that?

If you live in the USA and want to do business in Russia or just travel, a tourist visa may be your best choice. But get ready before you go on a trip, because getting  Russian visa is not so easy. Although I am an enterprising person, and most likely I will not have any problems filling out these applications without outside help.
