Yep, For 2 weeks for 2 people it's around £900 extra.
We did it and found it REALLY hard to use all the credits. We came back with 10kg of sweets too!
Thank you - we've done it before and really liked it, but we always order appetisers and never dessert and normally eat in the signature restaurants.
We don't normally do the dining plan but as it was free it seemed silly not to take advantage
We've just dropped the onsite part of our stay down to 5 nights so hopefully the cost won't be too bad
