You really cannot compare gold coast theme parks to disney. We happened to do both this year, as we didn't plan to go to disney at all so went to the Gold Coast in April. WHat a disappointed, especially Movieworld. We found it run down, Lethal Weapon is dangerous to your health, i totally agree. We vowed, the kids as well, that we wouldn't spend any more money on the theme parks in Australia, we may still go on relaxing holiday but won't spend any money on the theme parks.
Welcome back Ms. Shuttergirl, glad you had such a great trip.
I agree with the Sea World reviews, we loved San Diego. Is there much difference to the florida one? We are thinking of doing that next time, or maybe Discovery Cove. ANyone been to Discovery cove??
We didn't do discovery cove. When they first started the dolphin encounters at SeaWorld Gold Coast we did the blue lagoon on there. It was $50pp and you had to bolt as soon as the park opened to the counter near the ship and mini lagoon just past the ski show lake to book.
I like both SWSD and SWO. They are different experiences because although there are similarities they are still great. The Orlando one we actually spent 2 days at because we had a ticket that had that included that for no extra. You can do it all in a day though...but it is a full day.
Sea World Orlando is much bigger and has a 2 roller coasters. Kraken and the new one Manta. [So certainly will be a bigger hit for older kids/teens]
They both have Journey to Atlantis which is a boat/flume ride sort of like the Bermuda triangle ride (in style) and the GC. The Orlando one is more themed though and the 'complete' experience. It is a bit of a funny ride and be prepared to get WET. I wore jeans to SWO and they were wet for the entire day

SWSD has a rapids ride and a skyride (like the GC).
Both have the Skytower which is this rising viewing platform thing.
Both have a kiddy ride section but SWSD doesn't have a waterfront section.
Both have the Sea lion and Shamu shows
Both have a pets based show (pets doing tricks etc)
I had a quick look and it seems SWSD does NOT currently have a night time or Christmas show but Orlando does. I believe SWSD WILL be getting some next year though.
They both have much the same big animal exhibits (shamu, manatees, belugas, penguins) but SWSD has more small aquariums as well.
Anyone going to San Francisco and has time Monterey Bay Aquarium might be worth considering if you love Sea Otters like me

It isn't huge but I like it.
