In Comrie, Combruith (sleeps 48) is another option if you need to accommodate lots of guests together on a budget. There are also lots of good B&Bs, hotels and self-catering accommodation. We particularly recommend:
Fordie Estate lodge or cottages. The nearest alternative (luxury) accommodation, most of it a short and pleasant walk from the Croft.
Here is a little orientation map we've sketched up on google to help if you've not visited yet.
