Hi patb and welcome to Cruise-Chat.
I agree about the surprisingly minimal amount of closet space in Solstice. It's a beautiful ship but we also found it hard to believe that women designed the cabins. If all the women did was suggest the foot bar in the shower, they needed to look at the space a little better.
We found too that the lawn, while a novelty, wasn't a big deal. While I didn't actually witness anyone having a picnic or playing bocce ball, if that's something that passengers really like to do while on a ship, I can see the lawn's value. But expanding the seating for the glass show sounds like a better use of space to me, too...
