We booked for four people to stay for one night over two days on a short break. It wasn't cheap.
One thing to point out is that once you book the break there are no real obvious prompts to book things.
Book your breakfast, book your dinner and book the pool ahead of time because upon arrival it's a first come first serve basis and almost everything is gone.
The package doesn't include Fast Track so when you get to a ride you can wait anywhere from 20 to 90 minutes.
On day one my kids didn't get on a single ride.
So with day descended into a stroll around the park to see animals we called it a day and booked into the hotel. Note you can only book in from 3pm.
Once in you get a TV and some facilities in your room. The room is actually not bad with great views (Safari Hotel).
But this won't alleviate the issue of boredom. They boast an evening of fun for kids, except there was no real evening of fun. No disco, no meet and greet...nothing.
Chessington is an exercise in tediousness, mediocrity and doing home things without the comfort of your home.

You've been warned.
