I don't know much about lighting either, I would go for package 2. I don't think you need the robotic lamps.
Does music have to end at 11? I know in cabo it does, but I'm not sure about cancun, but that would be good to know.
Also, susan, I know you've been there before, could you tell me about the nightlife at dreams. I mean, I know its a family resort, so I know its not like spring break, which is a good thing, but how late are the bars open and do any of them have a dj at night or any entertainment. I'm just trying to think about after the reception or if we just do dinner and no private reception if there will be something for us to do in the resort.
