With regards to Rumjungle, they were easily able to set up our group of 25 guests. We used the "pod" that was the first on the right as you came in. There were four tables for guests, two that sat 6 and two that sat 8. Joe and I had a sweetheart table in a corner booth.
The last table that was up against one of the water walls was big enough for our signature picture mat, the cake and our card box. We didn't have pro pics taken at dinner, so let me see if I can get some from our guests.
Definately go with the Rodizio package. Our family loved it!
