I don't want to rain on your parade or anything but this particular GG experience has not gotten such great reviews and I also have a good friend of mine who did it with her cousin as part of a bachelorette thing and she didn't recommend it either...
Here's a place for some reviews of all the GG experiences:

Here's a snippet from my TR in case you're interested in the Safari Dinner-
We take the monorail to the TTC and then the bus to the AK.
So, heres a little background on this dinner. Basically, as an intimate or Escape wedding, we do not get a rehearsal included. But I knew we had to do something so everyone could meet (most for the first time) before the wedding. I didnt want it to be just in a nice restaurant because I figured peeps wouldnt be able to talk very easily etc. I was trying to think of ideas that would be fun and different etc. I knew we qualified as a Grand Gathering, so I looked into those experiences and found the Safari Celebration Dinner. It fit all our criteria, I had seen great reviews online and the fact that we were doing our dinner reception at Jiko in the Animal Kingdom Lodge I thought would tie in nicely. There might have been other options available, but from what I could find, this fit us best. Basically your group meets up at Flights of Wonder with all the other groups (I think the max for this experience is a total of 150 peeps-which means all the individual Grand Gathering groups together). You meet right before the park is closing (we needed to meet up at 4:30). At Flights of Wonder your group is given a name (I cant even remember ours, I wanna say it was The Cheetahs or something like that, but I could be totally wrong LOL). Anyway, after a brief introduction to the experience and meeting your host, Mama Dasha, your group is escorted over to Kilimanjaro Safaris where you board the ride vehicles for your own private safari! Now, I think the trucks hold 32 people and we only had 20, so I thought wed have to share, but we didnt, so our families got our own Safari vehicle which was sooo cool. They take you through the safari slower than the regular ride does, but not quite as slow as say the Sunrise Safari (which we were lucky enough to have done on our last trip back in Oct of 08.)
So, after we go through the ride, we are escorted over to Tusker House for our dinner. We are shown to our table and we all find seats. The Safari Celebration dinner is buffet and the food is really delicious! Its similar to BOMA but I feel like it even had a better selection. Everyone LOVED the food. During the dinner Mama Dasha had a microphone and had all the tables announce what they were there celebrating. We were the only group there for a wedding so we felt especially
.special. There were family reunions and birthdays and retirements and military families. I have to say, it was nice to be with so many people celebrating such happy occasions. At one point DF and I were asked to get up so we could be introduced, it was a bit embarrassing (remember, there were like 150 people there) but it was all great fun. Then we were asked to dance and then a bunch of kids got up with us and some birthday people and we all danced, it was so much fun! I wish someone in our families would have taken some pics though!
So, the desserts they bring to your table and they were delicious. (Sorry, no food porn from this meal!) During dessert is the time you can go meet with characters (I know Timon was there and somebody else-myabe Pooh?) I was going to go with DF to get our picture taken with them, but the line was really long. They also have real animals outside at this time that you can go see and ask questions about. The night of our dinner there was a tiny owl. (I LOVE owls!) It was sooo cute! And no, I just realized I should have taken a pic! (I get so angry at myself sometimes!) and I think there was also a tarantula which was cool.
After dinner everyone gets taken back by bus to whatever resort theyre staying at. So, everyone who was at BW took the bus back with us. It was really a great evening, everyone really enjoyed themselves.
There are pics in my TR too, but they didn't copy/paste here....
While looking for something different to do as our "meet and greet" dinner we decided on the Safari Dinner as I didn't read one bad review of it.
It was loads of fun, the food was delish and you could wear a little white dress for sure (I wore a white eyelet number)...
I would just do your research before you book any GG experience. I think with people staying off property, you have to have a certain percentage staying on, like 80% or something.
Also, anyone on the dining plan can use 2 credits for a GG experience...
If you decide to go with the safari...you might even get your own ride vehicle!! We did! We had 18 people attending the dinner/experience....
