It is so convenient to barbecue at THV, we did, too!
You're at Kidani, right, because it would be out of the question for me if you were at Jambo. Able bodied people, well motivated because they like what they'll be carrying, at Kidani, maybe. This is absolutely a guess, 1/5 of a mile from the pavillion to the pool...but where will you be at the pool? You may need a key to open the pool's gate. If you like grilling so much, I would send people to cook, then all join at the cooking area to eat. That would be my suggestion.
I hope someone else chimes in, you are getting advice from someone who has not done it, but has thought about it. Our DGC are 7,8,9...my DSon would be willing to do ANYTHING for us, but I've not asked him to do it, it just seemed not worth the effort, and I love hamburgers on the grill!
