I suppose I fall between the two sides posting so far here regarding Frozen/Maelstrom. I liked the original attraction, except for the dumb movie at the end, but the movie was easy to bypass. We made the attraction fun with a few inside family jokes, though most aren't worth explaining.
One family joke of sorts started back when one member of our extended family was very young. She was a little scared of the polar bears, so we thought to growl at THEM, and it worked. Instead of disliking that section, it quickly became her favorite part! The tradition stuck. Maelstrom wasn't a WDW e-ride, but it had charm.
As for Frozen, the film's popularity made it clear WDW had to build a Frozen attraction. In the early days, lines to see the Frozen sisters ran 5+ hours long every day! Yet, at that time, the parks didn't have any Frozen merchandise. WDW lost a huge opportunity that year.
I sorta get why they put the ride in Norway. It mildly offends the WDW traditionalist in me, but it makes some sense, though I would have preferred a whole new area for Frozen.
The current Frozen is a missed opportunity for something that could have been much better. I've long felt WDW doesn't have enough exciting eateries to meet demand - or didn't. It was just dumb they didn't create a Frozen Princess character meal in a crystal laced magical 'ice' building. In summer, folks would just love to escape to an eatery made of 'ice' with frozen confections. St. Augustine's The Hyppo sells high quality frozen juice bars in traditional flavors like strawberry plus a seasonal rotation of unique combos w/ fresh produce: Avocado Lime, Banana Spice Rum, Cranberry Habanero, Mamey, Plum Mint, Orange Basil, Blackberry Ginger! Mmmm!
(Three hours south of WDW, is also the hugely popular fruit stand, "Robert is Here," which does (or did) steady business of fresh fruit smoothies/milkshakes. South Florida grows tropical fruits that can't be grown farther north. Again, huge missed potential by WDW: unique Florida, delicious, and mildly healthy.)
Does anyone else remember Disney's Healthily Ever After/Magic of Healthy Living campaign? Yet WDW's theme park food offerings/promotions/rollouts have been a continuous disappointment.
