Bonus fast passes???

[StacyPop]

we are at the park and just noticed on my Disney experience that they gave us 3 bonus fast passes! Asked the cast member and she wasn't sure but does anyone know whether we can use them in more than one park? We are in Epcot and tempted to use one for soarin but afraid I won't be able to use the other two at MK tonight if I do. If I can only use them at one park I'll save them. It says multiple theme parks and attractions and lists all the parks and rides.

They're bonuses you weren't expecting. If you end up only being able to use the one for Soarin', that's still better than how you started the day.

Wasn't taking them for granted. My son was ill last time we were here and spent most of his trip in bed. We were lucky enough to be able to have a do over so I wanted to be able to do as much as we could.
Does anyone know if they could be used in multiple parks?
