Hi. We purchased our php's at paramount travel last trip and we had such a good experience with them that we'd like to buy there again. I notice on their website they show four, five, and seven day passes. Does anyone know if they sell six day passes also? We bought seven day last time and have time left but I'm not sure if it's one or two days so I figured we'd just purchase six day tickets and we wouldn't run into any trouble. Can you buy six day passes anywhere? Thanks.
