What reservation modifications can you make online without calling in?

[Freiden8]

Not ADRs or FP+, but actual resort/ticket/dining plan add-on changes?

I've seen some people say they were able to add the free dining promo onto their reservation last year without calling in, and others who said they had to call in. So, I'm really curious about qualifies a reservation to being able to modify it online through the site without needing to call in to the call center, and what exactly can be modified. On the site it says..

Hotel Reservations – Frequently Asked Questions

Q.
How do I update or modify a hotel or package reservation?

A.
Depending on the type of reservation, you may be able to update or modify your hotel or package reservation online. Simply sign in to your Disney Account and go to My Reservations, where you’ll see a link for “Modify Reservation.”

I'm trying to decide if I want to book a room only reservation this go around. We are hoping for a fall promo, but I think a room only code would work in our favor more than the free dining, which needs to be a package... anyway, I'm aware of the hassle and wait endured by people last year and would like to avoid it. And yes, I am contemplating not even making a reservation until it is released. I am not sure how flexible we want to be with our resort choice though and if it comes down to not being able to apply anything later, we may just forgo all promos to keep our 1st choice. Also, undecided about booking ADRs one at a time or how important 180+10 is to me. ANYWAY. Rambling.

I had booked a package and was able to apply the spring discount online.

I had booked a package and was able to apply the spring discount online.

I should've booked that on-line as well...Would you believe that when I did book via phone, the CM quoted the full price, and although I had the "Spring Discount" pulled up on my computer, and my dates were correct,etc., she still said it didn't apply?
After a while on hold, she found it, and everything was fine.
Eighteen more days to go!

If you will want to get a free dining offer on an existing reservation, book a package. If you will want a % off room discount, you can book either a room only or a package. You SHOULD be able to do these online. Whether or not the system will glitch when you try this? Who knows; its the Disney reservation system, after all.

I was able to adjust my reservation dates (added days!) online.
Also able to adjust ADR times online too.

I have been able to modify a package reservation and a passholder's discount reservation online. I have not been able to modify a room only reservation that had the bounce back discount. And I couldn't modify a reservation booked through Orbitz. Once I have paid in full, I haven't been able to modify.

Thank you!

Anyone know whether you can cancel a room only reservation online?
