My daughter is keen on a museum and I'm thinking the V&A is a good option especially as it has a Taylor swift exhibition on.
Thinking of making a few days of it train tickets are over £100 for the day with a rail card.
Happy to drive to the outskirts from Gloucestershire. Slough is somewhere we have been before. Any recommendations of other places to stay which has easy access to London by train and not cost a fortune. Looking at a couple of days around the third week of august. Also any recommendations of accommodation. Thanks
