Toddler friendly places to stay in NI (with proper cot preferably!)

[Duplo80]

I was wondering if anyone knows of a good holiday home/hotel for staying with a toddler. We were hoping to go to the North Coast but anywhere else would be good to know about. We recently stayed a few nights in the South but LO wouldn't settle in the travel cot. It would be ideal to have a proper wooden cot but can't see anywhere that has one. Also a family room/suite or apartment would be ideal. Thanks for your help.
