Ah right, the Crowne Plaza. Then you're in luck - the Fields shopping centre is right opposite, as is Orestad metro station, to get in to the city. All the metro stations have access via elevator, so there shouldn't be any accessibility problems.

More thrilling and fun? I dunno, you could stand in the middle of a cycle lane in the rush hour, that's always a tourist favourite...

(Otherwise, what kind of thing do they like? It's hard to recommend without some direction...)
