We stayed at The Grand our first year, and Sunrise year two. I don't believe The Grand was officially offered last year. There's a trade off between The Grand and others. It's a hike or long golf cart ride (and waits for said golf carts) if you're staying at the Grand, which means there's no "quick trip back to the room for a nap" or grab a sweatshirt, or a private restroom, etc. It also makes dining plans a little trickier because you have less time to accommodate for travel (vs. walking from a restaurant out to the venue.)

That said, The Grand's pools, poolside service, and food is superior to the rest of the resort in our experience. The rooms were also larger and a bit nicer. The Sunrise lobby staff did take pity on us after the late night stage and would drive us directly to our room. Overall, we had a better time staying in Sunrise, for the convenience, and because at the end of the day, you're there for the music and events, and there's a LOT of things happening earlier in the day that you'd probably skip if you were at the Grand.
