September 2016 for the 2016-2017 touring season is the tentative date for "Aladdin" to start a national tour. Disney Theatrical wants to attempt to open the show in London's West End before mounting a touring production.
That's pretty much par for the course lately with DT productions, though I expect "Aladdin" to keep running on Broadway when the tour kicks off - unlike recent tours of "Mary Poppins", "Little Mermaid" and "Newsies".
I saw the Broadway show right after it opened - it's AMAZING. I'm looking forward to seeing the show at DCA this fall, as I've heard the Broadway production drew off many aspects of the DCA show.
Also, "Little Mermaid" DID tour, but after a serious reworking. It also toured with a largely non-Equity cast and was a subscription offering in larger cities with heavy subscription bases. We had it in DFW last year.
