We always get LOS passes. We drop off the last day, since our flight is around noon time. When we arrive our first day, we can't wait to get into EPCOT, since we always stayed at Beach Club in the past, and now BWV. We go to the parks every day...that's why we're there. We also do Pleasure Island, Blizzard Beach and DisneyQuest whenever we feel like it (perhaps a couple of hours here and there), and we like not having to worry about allocating days and "plus's". And we only go to WDW once a year, and perhaps may skip a year and do a longer trip another year. So, LOS works well for us now. In the future, as we spend more time at WDW, we may branch out and explore more of the Orlando area, and other ticket options may make more sense (right now, we spend a few days at Universal before moving onsite at Disney).
CarolMN said it best..."The best pass depends on your family's touring plans."
