Part of having an enjoyable night is having a few drinks that would allow you to take the edge off and truly unwind. Just having a drink in your hand is not going to be enough, though. You would want to accentuate the experience by having a smoke as well. A smoke and a drink is the optimal combination to help you relax, and everyone else in the limo is probably going to be doing something like this as well. This would result in a very pleasant atmosphere, but it would also create a number of breathing problems.
Smoke tends to collect quite quickly when even the smallest of groups involves a number of people smoking simultaneously. This is why any limo service in ac nj that you even consider renting out should have an incredible ventilation system. Too much importance is given to air conditioning that cools the car down which has made it so that many ACs do not replace the air in the vehicle. This can be really bad for your health, and it can also cause allergic reactions along with making your eyes water and eventually there would be so much smoke that you might not even be able to see the person that is right in front of you.
Opening the window is always an option, but it can expose you to the outside world which would ruin the bubble of luxury that you are trying to stay inside of right now. The amount of money you are paying makes it quite reasonable for you to ask for an air conditioning system that takes smoke out of the car and leaves the air inside nice and cool.
