If it will just be your husband going to the Pop, I suggest taking the Lynx 111 from the hotel to Downtown Disney, then hop on Disney transportation to the Pop. It will only cost 2 dollars each way or $4.50 for an all day pass. The only reason I say if it is him riding is there is about .6 miles of walking from the hotel to the bus stop. It only takes about 10-20 minutes to get there depending on how many stops they make. Another option is taxi's, but you are looking at (according to Mears site) a 28 dollar cab fare each way. I hope that helps and if you have any more questions about the Lynx line feel free to ask, I ride it everyday to go to college.
