It's hard to put myself in a newbie's shoes, but I just took my husband (adult newbie, grew up with Disney movies but not an active fan by any means) for the first time a few weeks ago for just 2 days. When I asked him what he liked best in each park, his answers were:
Magic Kingdom (full day):
- Monster Inc Laugh Floor (his #1 fave)
- 7 Dwarves Mine Train
- Festival of Fantasy parade (this apparently really exceeded his expectations!)
- Pirates of the Caribbean
- Rope Drop Welcome Show (he got misty-eyed!)
He was LEAST impressed by some of the "classics" though... small world, peter pan, haunted mansion, tiki room, etc. His comments were "cute, but I'm really glad we didn't wait more than 10 minutes for those" — there wasn't the nostalgia factor or emotional impact for him.
Animal Kingdom:
- Safari
- Everest
- Flights of Wonder
He LOVED this park, he thought it was beautiful. We were only there half a day and he would have stayed longer no problem.
Hollywood Studios:
- TSMM
- Star Tours
- meeting Chewbacca & Darth Vadar
- Star Wars fireworks
- Tower of Terror
He is only a moderate Star Wars fan, but he loved all the SW stuff! He generally liked Hollywood Studios a lot. He liked this park and Animal Kingdom much more than Magic Kingdom — I think the crowds and strollers turned him off.
We didn't make it Epcot — but I think he will enjoy it next time.
Frankly, I was surprised and fascinated by some of his answers. But overall he really enjoyed the WDW experience and we will be going back! (That was my mission. Operation: Husband Conversion!)
My best advice is make a plan you feel is solid in terms of avoiding super long lines and hassles and include a variety of different experiences. But then give your friend space to form her own opinions and connections, which may differ greatly from yours. It was super hard from me to restrain myself from trying to "sell" everything to DH as "the most magical thing ever don't you get it!?!"
