Has anyone travelled across the country via train/car for a concert whilst 8 months pregnant?

I’ll be almost 36 weeks when we go!

Being truthful I feel absolutely fine about the thought of it, but so many people have tried to warn me off telling me it’s a stupid idea!

We’d take a 3 hour train to London and our hotel is 12 min walk from the concert! This really isn’t a big deal to me but wondering if anyone has done anything similar and can tell me not to listen to other people? Or has anyone done this and wish they hadn’t?
