Illuminations: Rose & Crown has some patio tables. You can request one, but as far as I know you can’t ‘wait’ for one – when a table is ready for you, you have to accept that table or (afaik) you will be politely invited to dine elsewhere. If you get an inside table, you can go out onto the patio at showtime, you do need to stand in a designated area. You can also see some of the display from the area of Chefs de France that butts up against the World Showcase Promenade.
Wishes: Can be seen from some tables in California Grill, or you can go out on the deck and watch. It can also be seen from some tables at ‘Ohana, but there’s no ‘outdoor’ option at the restaurant. Narcoosee’s is right on the water; again, if your table isn’t up against a window you can step out onto the deck. Or, at any of the resorts housing these restaurants, you can watch Wishes from the beach area.
