I'm just really hoping that they can give some more life to Monte as it has shown its age to me these past few years.
I'm not quite sure how you improve upon the ride aside from aesthetic issues. When I rode it recently the ride was the same wonderfully thrilling shuttle loop coaster that it always has been.
As for Fiesta, the main issue is that it's probably the worst executed theme in the park, and this is only considering the recent Boardwalk upgrades. It feels woefully dated and tacky, not to mention barely shaded. There are a few queue upgrades that Jaguar could use (turning the fire effects back on, for one), and to be honest aside from refurbishments, the flats can stay put. As for new flat rides I have zero clue what they could put in that they don't already have/had. I guess a themed indoor music express would be nice, I just want them to get creative with this. Something unique.
