The swamp and bayou tour was okay. We just streamed down a swamp, nothing big. We saw some alligators swimming by. The boat was full with everyone from the bus. I would have liked it more if there were fewer people on the boat. As for the plantation, that was okay. They just brought you to a big house and we saw the inside. Just a redone house with non-original furniture. No pictures were allowed inside. The bus ride was more interesting than the tour of the grounds. They showed a video of the Laura Plantation and the bus driver pointed out some stuff. I wouldn't recommend either one of these. Just tourist attractions. As for the booking, a little confusing with when and where for each tour.
We only had two days in London and I thought this was an easy way to see most of everything with some sort of commentary. I like seeing history but most of the times I didn't know what I was seeing. Going on a tour like this make it easy to understand what I am seeing. I wish we had more time to actually see stuff. It was more of a see sites through the bus. I would like to have stopped and took pictures with the sites. But overall the tour guide was informative and we saw a lot.
