Weekend away end November

[2anddone]

Hi every year my best friend and I go to Milton Keynes Christmas shopping for the weekend and usually have a day in London at the same time it's our one weekend of the year child free so like to make it special.
This year we are going 25-27 November does anyone have any suggestions of Christmas markets, shows, light trails etc a train ride away from Milton Keynes that we could go visit please?
In the past we have watched a west end show, visited Kew Gardens Christmas and the Ideal Home Christmas Show. It doesn't have to be London but preferably no more than an hour away on a train from Milton Keynes.

There’s a great light trail in Northampton at Delapre Abbey. There’s also a craft fayre on one of the weekends and it’s been around about the end of November in previous years.
Hogwarts in the Snow is brilliant and there’s a shuttle bus from Watford Junction.
Woburn Sands Christmas Faye is usually around that time. It looks like they haven’t published a date for this year though.
