I have an upcoming trip to the UK from the USA. I would like to reach out to the hotel in advance before my stay to request my rooms be assigned close together. Rather than making an international call, I would prefer to do it via email. How do you get the email addresses for specific IHG properties? I couldn't find it on the IHG website. While I am interested in this in general for any IHG property, currently I specifically need the email address for the Hotel Indigo Cardiff.
