It is a UK tradition to go to a pantomime with children at Christmastime. Pantos are usually daft with the lead woman played by a man, with lots of ad libs and jokes. We went to Aladdin in Ely Maltings as we did last Christmas (different panto theme). We went a few days after Christmas and everyone enjoyed it.
Had we gone in Cambridge, it would have been much more expensive. The panto runs until next week. Great family fun.
