I said no. Last summer, a coworker told me she was going for with her sister and her neice's family to WDW and asked for some pointers. It was her and her sister's first trip, but her neice's family's second trip. I started giving her pointers, but then she said never mind that her neice was planning everything and said that since she had already been that her neice didn't want any pointers. Ok, fine. I did mention a few things in passing though, like the kids being able to wake up Tinkerbelle, using the back entrance through the RFC if the lines were long to get into AK in the morning, some really good TS restaurants, the
DDP, getting a birthday button at guest services, how to use Fast Pass so that you could have more than one fast pass at a time, the importance of making ADRs, some quieter places where they could find characters, asking to ride in the front of the monorail and getting a monorail copilot license, etc. When they got back she was talking about the long lines for rides and character and how they had to eat CS all week. Sure enough her neice didn't know to make ADRs, that she could let her daughters wake up Tink, when EM hours were, they didn't find Pooh and friends at the back of the English toy store, or Belle and Cinderella in the back of the French pavillion, didn't get her great neice a birthday button, didn't know you could use the boats to get from MGM to Epcot, so took a bus to a resort then transferred to another bus the day they wanted to get back to Epcot, didn't know about the Kitchen Sink, didn't know the best places to watch the parades, planned for only one day in each park, etc. When I asked her why they didn't use any of my tips, she said her neice said I was wrong: that all the characters that give autographs are always out in plain open view, that only monorail resort guests could use the monorail, that ADRs weren't necessary, there was no such thing as a birthday button and Disney never gave anything for free, and Tinkerbelle was never able to be seen, so you could not wake her up. They had a fun time, but a little research or simply accepting a little advice from someone who's been there and does their research would have made it a way better trip.
