My family never stops talking about this. If I made our entire Disney vacation Typhoon Lagoon in the Cabana, they would be perfectly happy. You get the mugs, which are invaluable. You get a large shaded area, which happens to be secure enough to wait out a short shower. (I don't think this is the case at Blizzard Beach.) All the towels you need, someone to bring food to you, storage for valuables, a cooler with water, nice comfy chairs with ottomans. It's just amazing. I read a book part of the afternoon and others curled up in the chairs for nap. We aren't usually pinching pennies too much on our trips, but we also don't splurge a lot. We will definitely do this again, though.
Take note that there are two groups of them. We were in #8, which is near the wave pool. It was a perfect location for our family. I think the other group is closer to Ketchakidee Creek, which may be preferred if you have little ones in your group.
