@RainbowZebraWarrior Your trip sounds like such a trial, I hope you and your DD have recovered.
For what it's worth, we live in Bath, and I echo what @JMAngel1 has said about the 'ShedFest' here. Just after work, or early innthe morning at the weekend, is bearable. We also have the night before the official opening as "Local Residents Night", where we get a discount and a quieter time.
Usually, the day trip coaches come in, drop off their passengers, and then park in designated zones. There are 4 or 5 zones. Last year, the Wellsway zone had 84 coaches parked along it, on a Saturday mid-morning. It's a lot of extra people, in a small city centre.
However, that being said, I do love to visit, when it is quieter. Many years ago, I stood in the shadow of the Abbey, at dusk with snow falling, and it stuck in my mind as such a perfect moment, with the smells of Christmas.
All going to plan, my DM, DSis and twin DNiece and DNephew are visiting this weekend. The twins are nearly 2, and have had a lot of health issues, so have never visited us before. We're planning on going to Whitehall Garden Centre, at Lacock, which regularly wins prizes for the best Christmas displays.
I am thinking of putting up a strand or two of Christmas lights, just to get us all into the spirit!
