The Magic Waters Of The Seven Seas Lagoon...

You might have to carry the bottled water in your checked luggage (maybe Customs & TSA might not allow on a carry-on bag), but I don't think anyone would quibble at the park over someone taking a small bottle of water. Cheers

Cheers..It would be the small plastic one ( Like Powerade ) and I would have it packed in my case..

Out of the Seven Seas Lagoon, I doubt you'll have anyone give you trouble, but you might want to rethink your choice. I doubt you'll catch an alligator in a "gator"ade bottle, but "wild" water in Florida is not necessarily very sanitary or safe. All Florida lakes have the potential to have snakes, alligators, and deadly bacteria (literally brain eating amoebas and junk like that) in them. While there is no known issue with any of these in man-made Seven Seas Lagoon, the lagoon is connected to the naturally occurring Bay Lake. I'm not sure that I would want to take a chance on having any Florida lake water in my house. I don't even want Florida tap water in my house!

the same bacteria that shut down river country

I think (but am not sure) that you could have issues with getting that through customs. Disney would not really have an issue with you scooping up some water, however be sure that you know what the regulations are as far as your airline & customs laws.

When we sailed out of New Orleans I brought my son home a jar of dirt from congo square (the birthplace of jazz) but I was worried coming through customs on the way back home because we had been out of the country inbetween.

Thanks Kristen..

Also the Wilderness Lodge is on Bay Lake, not Seven Seas Lagoon. My thoughts are exactly like the others here.

Yea, there is a reason they have no swimming signs and River Country shut down...if you're going to do it, take some rubber gloves or something and put the bottle in a plastic bag.

Ditto to the rubber gloves if you get water out of the lagoon. And think about sanitizing it before putting into your water feature.

Another idea, since you're staying at the WL, what about getting water out of Silver Creek Springs? It bubbles up in the lobby of WL, flows over Silver Creek Falls, and into the Silver Creek Pool. It's obviously magical because it comes out of the spring already chlorinated! Amazing, huh?
