Fast Lane Plus

Is the offer still open for pass holders to purchase fast lane and get up-graded to Fast Lane Plus for free?

I beleive that offer is for Platinum Pass holders only and yes it is still active. In park only, not online.

"Upgrade to Fast Lane Plus when you buy Fast Lane (in-park only)"

Not sure when you’re planning on going, but definitely worth it on weekends; especially on Halloweekend Haunt Saturdays.

Yep...we did it yesterday. It was the last park day of our vacation trip...and after we got off SV during early entry...it was looking like a must. We wouldnt have been able to ride much at all on Sat without it...place was PACKED. Ended up being well worth the added cost honestly.
