Open Question: Safely air conditioning a tent?

Family from all parts of the country will be camping for about two weeks. It will be around 90 degrees most of that time.

I would like to have an air-conditioned tent available. Some family members are getting older, there will be young children, etc. I considered an RV, but that cost would add up quickly.

I have an 18x10 tent and a small 5,000 BTU air conditioner. Is it possible to safely use the air conditioner with the tent?

I realize that air will escape quickly and it will not have the same impact as it would in a house, but that's okay - I'm just looking for something to take some of the sting off the hotter days.
Also, please avoid the "that's not real camping!" answers. I know what real camping is, I know this isn't traditional, etc. RVs and hotels are not options.
There will be electricity available at the campsite.
