I did the tour in summer of 2004. Like Tessa said, it was enjoyable but not earth shattering. It was great for my family since we had never been to Disneyland only WDW, but I knew a lot of the information they gave anyway because I am a Disney maniac.
Our tour guide was also not the best. She was nice enough but not super engaging. Tessa, I saw your picture and I think my guide was actually the person at the desk at Club 33. I will have to look through my own pictures.
Oh, and the special Tiki Room experience was that they take you in there about 5 minutes before the actual show starts and point out a lot about the show and then they hype up the fact that they have a “special guest” there to meet you and it ends up being one of the audioanimatronic orchids - they take it around and give you a peek at the internal workings. It was neat but if you have seen any of the behind the scenes Disney shows that show the audioanimatronic workings, you won’t be that impressed.
Lucnh was yummy and a great location though! And we met some nice people too.
