We've been to the Alton Towers every year since it started with the exception of covid. It's become a family tradition.
If you can do s Sunday night stay they're usually a little cheaper.
This year you get access to the theme park where most of cbeebies land is open and a few other rides but not any of the big rollercoasters, a choice of two Santa visits (we've done both and if you do go recommend candy cane lane in cbeebies rather than the mutiny Bay version) where an elf takes you through trees to a hut to see the Santa, evening meal and hotel entertainment, breakfast, waterpark access, golf and panto (Robin hood).
Santa, panto, swim and meals require you to book a time slot.
If you do go ask for jingle bells and pop badges for the children at reception and post a letter to Santa with your toom number on it, they'll put a reply under your door during the night.
We've also done Legoland and Chessington but they're nowhere near as good.
