We did this trip with Karl on 3-18. Excellent adventure for a first time into the everglades as we got so much info we wouldn't have known. Probably know more than the locals now. Lol.. Excellent tour guide. Very knowledgeable and funny. Made us feel at home. On and off the bus with plenty of bathroom stops. No boring times at all. Two boat rides. Saw sea turtle, manatee, rays and dolphins in one boat ride! I saw that this tour got rave reviews all over the internet and have to agree it's the best. I also saw Mark gets rave reviews but I have to say I prefer Karl. He should get a raise. Guy obviously loves the everglades and loves to share that knowledge. He's also a great driver. If you are concerned about this trip being 9.5 hrs and have a health condition, I have a bad leg and have to potty a lot. That was a concern. however, as i said, plenty of potty stops. Can bring food and drink to have off the bus, plus you get a great lunch. Lots of stops. Not too hot or cold. If so, there's shade. Walk was less than a mile. So don't say no to this trip if you are concerned about all that. Perfect activity plus rest. I would take a kid, seniors and somewhat disabled on this trip. Went by too fast. Saw lots of wildlife. Go for it and bless you, Karl, from Dennis and I. - Nancy Schmit
