We cannot book accommodation for you, but we will happily give you our advice.  Edinburgh can be outrageously expensive or surprisingly affordable: you just have to know where to look. Most group trips to the city can be categorized under the labels corporate, private and educational. A 'private' group, depending on their budget, usually require no special accommodation  requirements other than that their hotel is up to standard and should have no problems booking a suitable hotel. The priority for 'educational' groups, which are usually on the large size, will be their budget. To assist them we have listed the websites of all Edinburgh's backpacker hostels. 'Corporate' groups are here primarily on business and we have listed for them all Edinburgh's conference, exhibition and venue centres, plus hotels with inhouse venues. But whatever your group category we are more than  happy to advise.
