We did this tour last September. I agree with what everyone has said about the final breakfast. We were also fortunate that they looked for a room for us (without our even asking, and we arrived around 10:30 am) so we were able to check in and drop off luggage. One thing I would do differently would be to check out of the Mayfair and spend my last night at a hotel at Heathrow. We noticed that the tube trip into London is quite long, especially when you're sleep-deprived and wrangling carryons. We had them book us a cab the morning we left, which was helpful but much more expensive than the tube--about 80 pounds for the two of us, and even with a cab, it still took ages to get to the airport. Heathrow is a long, long way out of town. Having done a couple of these tours and always having to leave at dark thirty, I plan to stay that extra day and find accommodations at the airport from now on. We did it in Rome, and how nice to stroll out of our room and into the airport to check in without any stress from getting TO the airport. You will love how easy it is to get from the Green Park tube station to the hotel, and there are a number of little restaurants scattered about the area. Quite lovely, and easy to get about.
