The hotel agent has indicated that the hotels are happy to help with dietary requirements. The hotels generally offer a buffet arrangement for the meals, so hopefully it should be possible to find something suitable. The agent said that the hotels can provide further help for those with dietary requirements but it is unclear whether in practice this means giving advice on what might be suitable to eat from the buffet or offering a separate meal. It is also worth bearing in mind that staff may not always speak good English and hotels outside of the UK may not be as used to considering cross contamination, for example.
