I'm looking to go to London from York (or POP for free delivery) on Tuesday 11th of August. I'm wanting to do a 90 minute Palace of Westminster tour (need to arrive at least 30-45 minutes before for tickets and security) followed by Afternoon Tea at Claridges at 3:30 (already booked - approx 2 hours). I quite fancy I trip on the Emirates airline too but not sure how to fit it in (done London Eye & River Cruise before) after 7pm it's an extended 30 minute round trip, but not sure whether it'd be cutting it fine to get back to KGX. I'm taking a relative for their birthday. I already have a Two Together Railcard in preparation for the trip. I have a combi AmEx/Visa card from MBNA which are both contactless, can one of us use the AmEx and the other the Visa? Or is that frowned upon due to the same name on both cards (and they're both registered to my TFL account). Having not been to London since 2003 I don't know how easy it is to get around. I was just after some advice about my plans and travel within London, any comments/help appreciated.
