Peat Tours is the best!!!!! Highlight of the tour. I don't know about his policy on cancellations. Basically he doesn't ask for money till the end of the day. No credit card needed to reserve a spot.
You will have a great time with Peat. He takes you to the falls before the cruise ship people get there. He takes you on a great tour of the area. He then takes you any where you want to go. He dropped us off at the ship for lunch. Then picked us up and took us down town. When he came to pick us up - we were not ready and he said no problem. He hen at the end dropped us off at Margaritaville, which is only a 10 minute safe walk to the ship. Only when he dropped us off at Margaritaville did he ask for money.
