Yes ADR's are for Table service only. I plan CS, but if it does not work out we do not eat there. I always plan all of my TS, because it is diappointing to decide to you want to try something & they tell you they are not taking any walk up's. Especially if you want to eat at CRT, then you have to make PS for that. At some of the resort's it is easier I find to walk up, but Ohana is getting pretty busy these days. Maybe after your first day if you can plan alittle better where you want to eat, then call dining from your hotel. At least I would call in the morning from whatever park you are at. You can go to any phone & hit (oh I forgot what to hit, but someone here can probably remember) & make your PS then.
