Since stollers are not welcome and having the experience of holding an infant for 3 days in the entrance way of a sports stadium, my thought is:
Option 1: "Screw the assembly, stay at a hotel that is kid friendly (preferrably not on the list of Motel 6's), must have a pool (age appropriate), send husband over to pick up releases. Go shopping and tell the husband you expect a dinner at a high class restuarant, and hire a baby sitter for an hour and a half.
Option 2: Rent a motorhome and stay in it during the sessions with the kids and listen to the program on 98.3 FM while watching Veggie Tales and enjoying the AC, refrigerated drinks, and lack of lines for the restroom. Return to 5 star Hotel room, tell the husband you expect a dinner at a high class resturant (you deserve it) hire a baby sitter for an hour and a half. Oh, don't wear the damn convention badge.
Option 3: Just book a hotel on Hotels.com even if it is in the city you live and not in the city of the convention, forget the assembly, take a break, enjoy your family communicating together, go to the aquarium, zoo, pool, beach, children's discovery, enjoy 5:00 p.m. drinks, dinner at 7:00, orchestra, and breakfast etc. Sleep in late, have room service, Return home on Sunday-Monday, and feel the spirit giving you renewed strength. Comment at the convention review part that it was the best convention you have attended, but there were too many good points to recall just one. (If you have children they will believe you)
Bingo; any beautiful "sisters" with kids want to go to an assembly with me "my style". I do have more ideas.:)
Just saying...
