Does anyone know whether if you can participate in a Host Quest (i.e. VMK Fun Time Quest) if you're in the process of finishing another quest? I'm stuck on the Fireworks portion of the Autopia Quest and want to try one of these, but I don't know if I would lose any progress (I'm not playing Haunted Mansion again or for a while!) Thanks for the help

No sorry kido one quest at a time but u should quit autopia bc they ain't goin anywhere but the HOST's they've got the goods and its a one time deal
(sorry for talking like i'm from a bad 20's movie)
:CastMem:

heres a tip to fireworks get someone to change fireworks and someone to click fireworks i did it with my dad and we got silver rocket pin for it

You are allowed one quest at a time. It does not matter if it is a guest made quest, staff made quest or or one of the game quest such as the diver suit quest.

Only one quest at a time, sorry but either you have to wait or use another account to play other quests. Staff allows one person per quest even if you have 50 accounts but if you are stuck on fireworks that would be your only option of playing any quests until you get past fireworks.
Unless quitting is an option, doubt that.

It's not possible to do two quests at one time. However, you can quit the quest, do that quest, and start the other quest where you left off. (Example: I'm currently doing the last Autopia Quest, but I can quit that quest and do the Fun Time Quest. Then when I'm done with that, I can go back to the Autopia Quest Track, select the quest I was doing earlier, and click start. Then I will start from where I left off.)

quit driver quest and do staff.. if you try again driver you get same part -3

I know I can quit the Autopia Quest, but I'm really not in the mood to go back and play the Haunted Mansion Game part (granted I'm not sure at which part it would take me back to if I quit).

well if u quit u will be in the sane spot

but wait? isn't the quests going to be under the "Q" button? and right now there are those two under the "Q" button about finding the hidden mickeys and that trivia type one. The Autopia one is accessed from the quest track double clicking on the thing, same in captain's quarters, and the space one. What im trying to say is they are accessed a different way so i would think you would have no problem right? :)
