We kind of struggled with that one ourselves. We timed it so we'd be using FP #1 at the very end of the window and FP #2 at the beginning... then buy a toy, restroom break, eat at Woodys/take our time, then FP #3 as soon as available.
We were close to leaving the land for awhile - wouldn't have been the end of the world but not all that convenient either.
A few of the Adult Lemonades made the wait enjoyable.
It was cloudy on our day so no concerns with heat/sun. If it had been all sun, we might have left the land, gone to the Frozen sing-along show (or something like that) and come back later.
