I would advise Leopoldstadt. &Juliet and Some Like it Hot will almost assuredly tour, so just in case you don't make it back before one of those closes, you'd still have future opportunities to see them. With Leopoldstadt, they haven't announced any casting changes yet, but usually when limited runs extend as long as this did it results in at least a little turnover, so even if you're back in the Spring, this will likely be your last chance to see this full cast.
