We were staying at the Marriott over Christmas as we currently live in the US and were back visiting family.
It was a shame that as of 24 Dec - and with no prior notice, the dinner menu was reduced drastically, removing a number of dishes that my wife - a coeliac who must have gluten free food, could have eaten which resulted in us having to rely on gluten free snack items (quiche and crisps) from Tesco.
