Thanks for the replies on the fare price. It sounds as if their initial rate is a little higher than most - but that it includes all of the fees and tip, which probably evens everythng out.
Were you able to make a free grocery stop with them? I know at least one company charges a fee for stretch limo grocery stops.
We are kind of in the same boat when it comes to just wanting to do it because the kids would think it was cool. There are 7 of us travelling in 2 families, so if we do one way we are only looking at about $60 or $70 each, which is about the cost of a bottle of water. I'm justifying the cost of the limo trip by pointing out that we can do a grocery stop to get a couple cases of water and some snack food, which will save us a ton of money in the parks. However, the real reason is I just think it would be fun for us and the kids.
