I've called again, apparently they've (hotel manager) now gone home for the night and will respond tomorrow. I am lost for words.
Thank you for all your advice, I think bearing in mind our circumstances the walk to another hotel would be the best option for us, I don't want them to suggest the HI Maldives though as its not comparable. Would it be reasonable to refuse this and insist on something of the same caliber as the IC Hotel?
