I thought I'd surprise my DS with an in-room gift on our upcoming cruise. I was looking at the Entertainment Bundle, (back pack and speaker). Back pack looks nice in the picture, can anyone give me a firsthand review if you have gotten it. Is it a good quality back pack? (is it more like the material of a school back pack, or is it more like the nylon drawstring back pack?) I hope you understand what i'm talking about. Any pictures you have of it would be appreciated. Thanks for your help.
