I don't feel this way, most of things on are overpriced rubbish. Tacky, meaningless and hollow, to be honest. I try to take mine to a play and a ballet every year, not the pantomime. We have lots of our own traditions as a family, but must of the advertised things are a waste of money. I've had children for 13 years now (still have very little ones too) and over that time we have tried a few winter wonderland type things, centre parcs, stately home winter lights walk, pantomime, Santa's grotto, christmas train ride and all of them it was a one time thing, never to be repeated. Overly crowded, noisy, tacky music playing, just dragged down to an empty, consumerist, low-brow, painfully modern experience.
The simple, traditional things are much more beautiful and magical experiences I've found, carols at a local church (cathedral even better), brass band, carols around the tree, wintery walks with friends/family, beautiful plays and ballets without all the crass jokes and TV references of panto. And all the good times at home besides - reading Dickens around the fire, baking mince pies and gingerbread, making Christmas treats for the garden birds.
My SIL just posted pictures and videos of a Christmas ice skating disco shes taken her children too.. all Glow sticks, sweets and Mariah Carey. It looked ghastly! My girls are doing watercolour christmas cards and singing Gaudete (and the baby is grizzling over the singing, and my toddler is trying to destroy said watercolours - not trying to appear sanctimonious!)
Stick a more wholesome theme OP and save yourself the wasted cash.
