As Zulaya pointed out, getting a patio table is a crapshoot, but don't let that deter you! 7:30 is the perfect time for a PS, and we have made PS for that exact time in the past. I would show up about 15 minutes before your PS and politely request patio seating. If you get the patio table, you can draw out your dinner (share appetizers, have an entree, and then enjoy dessert) and you should be eating your dessert when Illuminations starts. If you don't get a patio table, just order an entree, and then bail out of the restaurant and you should still have time to stake out another viewing spot. As far as view from the patio, I think most seats are pretty good. Note that the umbrellas on the tables in the lower patio, if you are on the upper patio, will obstruct your view, but the wait staff will lower the umbrella's before Illuminations starts and the views for those in the upper patio are great.
