I contacted several companies for group rates and locked them in - I think it was between 60-80 for the day rental including gas and insurance - the info is saved on my work pc. I think I had 9 jeeps at the time and told them there may be more. It is right at the port so we don't have to go anywhere.
I got some great info from cruise critic...a sample tour of the island. I was going to map it out and send to everyone before hand so we everyone could decide what they wanted to do, Aruba is not a large island and the only thing we would have trouble seeing is the natural pool as I read the best way to get there is on horseback. But they say the whole thing is super slick and I could just see my two falling.
