A friend would like to travel from London to Bournemouth on Firday 10th July after they finish work around 1700, and return the following Sunday afternoon. I've advised the purchase of a £37.55 Off-Peak Return (with Railcard) which I think is valid at this time, its difficult to check till I'm back off mobile tomorrow. Can anyone please advise of which trains are likely to be the least busy? I'm aware that might be asking a lot given it's the busiest time of the week and July. 10 or 12 car trains? And is there usually space right at the front of these departing Waterloo? Also again it's tricky to check on my phone, is there any engineering work on the Sunday? I'm not particularly familiar with this route, any other advice appreciated!
