I don't subscribe to TGM and I don't know whether he made that statement universally or for a specific situation. If he made it universally, I completely disagree. If he made it for a specific situation, then I really can't say whether I agree or disagree.
Here's the deal.
If you're on a 7 day or so trip or as most of us are, AK becomes about a 1 day park. That means you're going to have to make some choices. Or even worse, what if you're on a 4 day trip and have only 1/2 a day for AK or less. On the one hand i'm going to say do it. On the other, I'm going to say skip it.
Now when we went to Rafiki's it was fun. We got to see a meerkat surgery. Plus there's a dark sound booth you can listen to forest sounds with. One of the caretakers will usually come out with an animal and give a talk. Rafiki is there. One of the characters from Playhouse Disney was there too. There is the petting zoo and that isn't anything special. But the issue is time. Rafiki's can take up a lot of time and it's usually in small increments here and there and you don't realize it. We burned about 2 hours doing it. 5 minutes waiting for the train, 5 minutes on the train, 15 minutes to walk to the place (stopping at the little demonstrations along the way, 5 minutes snacking at a well placed snack cart, 10 minutes with the characters, 5 minutes in the booth, 10 minutes with the animal they brought out, 10 minutes in the petting zoo, and we watched the meerkat surgery. 5 minutes to hike back to the train, 5 minutes to wait (On busy days the waits can become a full trip or two. We didn't get to do a couple of other things because of it and we didn't have all that much time in Dinoland.
Now depending on what's going on that day, you might not get to see a surgery or the characters or have the caretaker bring out an animal. And if none of those are going on when you go, well make your own judgement. Next time we go, I'm going to check and see if there's a board as to what's going on there that day. We didn't see one or know until we got there. And I don't think I'd want to go if nothing was going on that day.
And hopefully, the Gators will become shoes and luggage tonight. LOSE EDDIE MUNSTER LOSE!!!!!
