I don't normally save up for trips to KI, but it's an easy day trip and all I usually spend is gas money which is split between everyone in the car. We have season passes and pack food and drinks in coolers. Next season will be different as we're getting the Platinum and going to be heading to Cedar Point for a couple days... not sure how we'll pay for it yet, probably just start setting money aside a couple months beforehand. Also haven't decided where to stay, we thought about splurging and getting a really nice hotel room, but then we thought all we'll bedoing there is sleeping... I would rather spend the extra money on souvenirs.
