I rode in a limo to the wedding of one of my sisters. It was very nice. All the bridesmaids were in it. Very roomy and quite plush. I loved it. The ride wasn't long enough, if you ask me.
I've been in a limo once; for my wedding. It wasn't the best experience. There was supposed to be a bottle of champagne in the back, but we didn't even get a bottle of water. The driver got lost, and had to stop at a gas station for directions. He was nice enough however to purchase some bottled water at the gas station for us. The seats themselves weren't the most comfortable I had been in, and even though the seats went all the way around, it was difficult to move around in the back while the limo was moving.
