BOG tablet ordering and fastpass+

[disneycrazymama]

We just secured our March 13th BOG reservation on the BOG fastpass+ website! I chose the pre-select meals option thinking it would expedite the line etc but my ds is disappointed! He was really looking forward to ordering using the "rose" and the touch screen!

Anyone know if we can make changes using that system when we arrive to satisfy his excitement?
Thanks!
