We will be in London in Sept with our university age son, traveling from Canada. Husband will be having a mid-50s birthday while we are there. Two years ago on his b'day we were in Munich and did a Mike's bus tour to Neuschwanstein Castle. Which was awesome and memorable. The year before we were on a plane to Ireland. Last year we were packing for Italy. We seem to be making a habit of traveling on/near his birthday.
I am thinking of the "London Walks" trip to Stonehenge. That day is their "Salisbury & Stonehenge Autumn Equinox Season & Flower Festival".
Any other suggestions for a memorable possibly unique but not overly expensive way to celebrate? Besides the fact that we will be in London/UK for the first time. I am thinking about cost of no more than 50-60 pounds each (x3).
I know that's pretty wide open but I am counting on those who know London well to have some ideas. We are always up for quirky, adventurous and fun. We are running a half marathon at Kew Garden the day before but I wanted to do something on that day as well (19th).
Thanks in advance.
