If you're going by car you also need to add £3.50 per day for parking at the hotel. The castle is £6 to park at, though there's an opportunity to park elsewhere in Warwick and walk. Good price at £88.
Can I book 2 adult and 2 kids but actually go 1 adult and 3 kids?
I have just used a different browser and gone right through to payment and its £88 for me
I just did the same (as a test) and also got £114. Update - did it again and got £88. Maybe check you selected Family Room. Did it a few more times and getting £88 each time now.
Just tried it now still £88?
