I love the Mickey Mouse pillow cases on etsy but afraid to order one for my Grandson. Do boys around 8-9 think that it is UN-cool to sleep on a Mickey Mouse pillow case with autographs (even if it's Mickey with a pirate hat on)? My Grandson is very into watching sports and loves to go on the rides at Disneyland, just not so sure about the whole Mickey Mouse thing. It's a no brainer for my young grandaughters...they'll be so excited! We're taking our Grandkids on Magic cruise. What's your opinion/experience with elementary age boys? Thanks!
