DS has always wanted to go to London, mainly because he is fixated on the transport system (he has ASD).
I've booked a few days for the 2 of us in June, arriving at Euston on Tuesday afternoon until early Friday afternoon. Our hotel is a 10 minute walk from the station.
His wish is to see Tower Bridge opening, go on the Eurostar, visit the Lego store and the transport museum. He would like to use all the "real" transport to get around (bus, subway, river bus) and possibly go on the London Eye and a tour via bus or boat but these are not essential.
The stinger is, because of our location and finances we are unlikely to be down there again anytime soon so I've already booked a day trip on the Eurostar which will take up Wednesday.
Any advice about travel passes etc would be very useful too, I've been looking at visitor Oyster passes which seem like good value?
