Like Joe Camel, I always book my hotel room through the Universal internet side, just click on hotels and the Stay More Save More special. That will give you the seasonal rate plus the percentage saving with 6 or 7 day booking. And you get the Express pass for both your hotel arrival date day and your hotel departure date day. So if you're staying 6 nights, you can actually use your Express pass for 7 days....5 days cancellation policy there also.....Yes, as Coasted says, 7 nights discount is the best percentage, but the percentage changes depending on the season. Since you're going in September, that's usually the max discount. You need to book soon though, since Universal hotels fill up early now
