I just booked the ESW trip for 2020. For the first time, I'm using my Gift of Time day at the end of the trip, rather than the beginning, as I feel it would be more useful in London than Edinburgh.
While it's still too early to book the flight, I did a quick search and there's a paucity of flights arriving Edinburgh before 11 AM, Tauck's arrive-by time. Curious what people have done who booked this trip. Did you extend the trip on both ends?
