We are in Dusseldorf for a week and won't have car access except in the evenings. It looks like this hotel is not too near the city center and we'd need to take a tram or something? I'm a little worried about expensive to get anywhere and do anything from this location(picked by my husband's work--he'll be off in Mulheim each day).
Are there nice things around that are walkable?
Would they have kid size bikes at some local bike rental?
How exactly do we ride the tram(I know this is silly, but do we just pay with cash when we board, are their ticket stations, exact change?, an all day or weekly pass option?)
This is for myself and my 8 yr old daughter. Thanks!
