After 10 nights in Scotland, our current plan is to spend two nights in York, then a late afternoon train to London, spending our last night at the Hilton at Paddington station (using points), then flight back to US at 2:10 pm the next day. We won't really have much time in London except for dinner and a couple hours in the morning before heading to the airport.
Now I'm rethinking and considering spending the last night in York (3 total), then taking the 7:30 or 8am train to London, Heathrow express, arriving at the airport at least 3 hours before our flight.
Thoughts? Keep the original plan, or spend another night in York?
