You'll love having the CDN passes. We got them in 2001 and 2002. Knowing that we had to use them or lose them was great! It gave us the freedom to come and go as we pleased.
On day, we planned to just visit AK in the morning and resort hop the rest of the day and night. We ended up staying at AK late in the afternoon, rested at the hotel around dinner time and we too tired to resort hop. ds got up from his nap at 6pm and the rest of the family was well rested so dh came up with a great plan of us going by Epcot for dinner. We ended up seeing ToD and Illuminations! What a lovely surprise. Having a hopper is great.
I loved just coming and going and not having pressure to see it all in one day. We would just go over to MGM because dd wanted to go on ToT. We would spend about 2 hours there. Rest, play and maybe head to another park for a couple of hours.
They are great passes! We ended up visiting MK 4 times, Epcot 3 x, MGM 3 or 4 times and AK once or twice in on vacation. S
