Does anyone know what size linens I should bring for my bed? I've heard that the size is either Twin or Twin XL... Does anyone know the difference?

just bring a twin

im assuming the 'xl'(never heard of that before) is for those who requested a longer bed due to their height

I seem to remember it just being twin... If you have a bed bath and beyond near you, they had a whole book that told you the size of each residence and the bed size!

Ikea's twin size fits the bed and is also reasonably priced!

Twin is the standard, and twin XL just means that the bed is longer to accommodate the tall people.
