I'm planning a trip for my parents and myself to London in October. We're going to stay in London for about a week and take a few day trips (one organized bus trip and then Bath and Portsmouth on our own). I've been trying to figure out how much round trip train tickets will cost for the Bath and Portsmouth trips, and I'm completely confused! It seems like every time I enter the trip into a website, I get a different number, particularly for the trip to Bath. Anywhere from 26 GBP to 100 GBP. Is there a system to the varying prices that I haven't figured out? How much do I really need to budget? Any help would be appreciated!
Thanks!
