To cut a very long story short, I may have invited my brother and his fiancé to come with us next year on our Disney trip. Not only that, to cut costs I may have suggest we share a room!! Am I mad? It is going to cost in the region of £1,300 each next year (including the dining plan if we book before July 1st) whereas the same holiday for just us two would be around £2,500 each. Are we going to end up hating each other by the end of the holiday? Is it worth looking at an extra room? Any experiences with room sharing?
