Which restaurants can you see the fireworks from and what time would you advise to book the table for?
It depends on what you mean by "see IllumiNations". Several of the restaurants have a view from
some tables, but no restaurant is going to guarantee you a view from your table. So if seeing IllumiNations is important to you, I'd have an early dinner and then find a spot somewhere around WS to watch the show.
Your best bet is Rose & Crown because they have a reserved viewing area for guests that do not have a table with a view. Your server will take you out to the reserved area to watch the show and then you can return to your table afterwards to finish your meal. The patio tables that do have a view have an excellent view, but they are very popular and R&C generally does not allow guests to request and wait for a patio table (you must take the next available table or forfeit your ADR). I would probaly aim for an ADR around 7:30 pm for a 9:00 pm showing of IllumiNations.
The next most popular venue for IllumiNations dining is La Hacienda. Some of the tables have an excellent view, but most do not. Again, they generally do not allow guests to request a window table, but if they do, make sure you specify a table with a view of IllumiNations because there window tables that do not have a view (they face the wrong way). There is no reserved viewing area, so if you are a table without a view, you will miss out on parts of the show.
I haven't been to Spice Road, but I've heard/read that several of the tables have an excellent view of IllumiNations.
Several other WS restaurants have some tables that have some type of view of IllumiNations. Monsieur Paul and Tokyo Dining come to mind for the TS locations. At Monsieur Paul, a few (and I mean, like four) tables by the window have a limited view of the show. Most of the restaurant does not.
