Just booked one nights accommodation at Alton Towers Splash Landings Hotel for £35 per room including breakfast and entrance to the water park. There are a number of nights available but these tend to be on a Monday, Tuesday, Thursday and Sunday. To get this price book through Lastminute.com as you will end up paying £55 if you go direct to altontowers.com.
If people are unsure if accommodation includes waterpark entrance then check out link below:http://www.altontowers.com/pages/water-park
Hotel guests can book a Waterpark package and get unlimited use of the Waterpark for the duration of their stay.
We booked the same deal last year which worked out quite cheap as long as you dont eat in the restaurant. You cant check into your room until 3pm but you can still arrive early to make use of the water park.
I know a similar deal was posted earlier in the week but this is £20 less and includes water park entrance.
