Question: I know we can reserve a room, or reserve a seat, but can we reserve a train or reserve a hotel? 

Answer: If you have enough money, then you can pretty much reserve whatever you want anymore. Well, every hotel and/ or train is going to be different- some will say yes, and some will say no. But you STILL have to be able to pay for it, so yes you do need to be talking about whether or not you can afford it. Sory if my answer wasn't correct, but I only saw the question - I didn't see a question about your grammar.
