Anyway, here are ours, interested in seeing others':
DHS: Disney Channel Live
Animal Kingdom: Flights of Wonder
Magic Kingdom: Hall of Presidents
Epcot: Living with the Land (close second: Kim Possible)
DHS: Used to be backlot tour, now I suppose One Man's Dream. I suppose thats not a "high profile"
EPCOT: The mexican boat ride! Love that thing, why? No clue. I only like riding in the front seat though. Also love living with the land but fam hates it.
AK: Mind is blank. only been twice.
Epcot: Living with the Land - love the relaxing ride through well-crafted scenes and wonderfully interesting farms.
AK: Dinosaur! - I say low-profile because it's oft-overlooked as one of the best rides in Orlando.
HS: Sorry, nothing to list here as I've only been there once and left early.
Epcot: Virtual Shuffleboard! Ok, it's not really called Virtual Shuffleboard, but it's one of the games you can play after you get off what's left of SSE.
AK: Jungle Trek in Asia, the scenery is great to walk through.
DHS: Sounds Dangerous. Ok, I kinda thought it was neat, and a good place to take a quick nap when they cut out all the lights. Best part is that you can snore and nobody would hear you :)
DHS: One Man's Dream and Muppetvison (just because there are so many 3D Shows out there)
EPCOT: Living with the Land hands down! Actually, that whole pavilion
AK: Flights of Wonder, Marajahah Jungle Trek, and Pagani Forest Trail
AK- Flights of Wonder - I actually got picked to go up on stage with my video camera and was able to film really up close - it was cool!
DHS- Prime Time cafe - always go for a cocktail in there and have a little down-time, spend ages trying to take the perfect photo of the luminous ice-cubes.
MK - People Mover, never used to bother but my mum always loved it - now I do too! nice to have a rest and see Tomorrow Land from a different perspective.
EPCOT- Mo-Rockin, the band in Morocco, really good to listen to whist nibbling on something at the Tangierine Cafe.
DHS: Gotta hand it to the Great Movie Ride. Despite riding it tons of times, I've never once waited in line or had a full car.
Epcot: Ellen's Energy Adventure. I LOVE THIS RIDE. The only way to start the day at Epcot. I listen to the main theme every-day.
Magic Kingdom: Tomorrowland Transit Authority. Wonderful ride with great views for the whole family.
Epcot: Maelstorm at Norway. Rarely a line more then 10-15 minutes long when we go and it's a childhood favorite.
Hollywood Studios: The Backstage Tour is always a favorite along with Muppetvision 3D. Yeah everyone has a 3D show now, but DHS has the muppets!
AK: Wouldn't know, I've never been impressed with the park so we rarely ever go.
MK- Tomorrowland Transit Authority. Funny how most of us have picked the same thing. For me it's nostalgia. It was the first attraction we did, the first time we took my daughter. Now it's tradition.
Epcot- Maelstrom! Does this qualify, given the fact that it offers Fast Pass?? My other favorite- Kim Possible missions. An often overlooked, completely new and fun way to visit World Showcase. It's a bit time consuming, and I wouldn't recommend it if it's your first time to Epcot- but it rocks!
HS- One Man's Dream. I hope they don't close this. I heard it was scheduled to close last year, but some influence from D23 kept it open, at least for the time being. Does anyone know if this is true?
AK- DiVine. I think she's one of the best attractions anywhere in the parks!
AK: Wildlife Express Train. You sit down and get out of the heat! Also you see backstage into the cages and what not.
EPCOT: Journey into your Imgination with Figment...I know I know but now lines and you get out of the heat!
DHS: Mulch Sweat and Shears. Awesome funny group that plays on Streets of America.
EPCOT- Spaceship Earth: It may be the icon of the park, but it isn't a star attraction. Still, a pretty fun ride.
DHS- The Great Movie Ride: Gotta love seeing classic movies from the past. Also, the integration of live actors is a nice surprise!
AK-Festival of the Lion King: It may have been a bigger attraction a couple years ago, but these days, it is a hidden gem that never fails to entertain families.
MK - probably the lowest key attraction...playing a game of draughts (checkers) outside the candy store on Main Street. Its a grand tradition for us.
Animal Kingdom - either of the forest trails. Great way to see the animals for as long as you like without lining up for the Safari.
Epcot - dont go enough to even really have a favourite main attraction let alone low key.
Magic Kingdom - Astro Orbiter
EPCOT - Living with the Land
Hollywood Studios - Voyage of the Little Mermaid
Animal Kindgom - Pangani
Last time I was on the Great Movie Ride (GMR at DHS for those in the know), the ride stopped for a solid 15 minutes right when we were in the Wizard of Oz section. It was fun at first and then it stopped being fun.
Oh and to stay on topic of this thread, I feel like many of the trails at Animal Kingdom are under the radar. Many people are there to go on rides and see shows, but some of the trails are so incredibly themed and populated with amazing animals. That is why I feel like Animal Kingdom is really a park of discovery. I feel like there are lots of nooks that people are walking right by.
If you've not had the pleasure of visiting Tom's island, well, it's like the Jungle Cruise if you added caves, a restaurant and literate crew people, then removed all those pesky hippos.
