回复：请大侠推荐去这几个地方一日必游的三个景点

第一日：Toronto开到Ottawa，去Ottawa 。。。？
==>It'll take you half day to get there. Any way, you can take a walk around the parliament building which is beside the river; it's pretty.
You don't have mush time. Visit a museum or two.

第二日：Ottawa 开到Montreal， 去Montreal 。。。？
==> Hike to the top of Royal Mountain (in the middle, there's a great overlook to see the city. Oylinpic site, where you can take an elevator and go up to a high tower and have a great view of the city. Also, there's a beautiful garden nearby.

第三日：Montreal开到Quebec City(再开回Montreal)，去Quebec City 。。。？
==>Just walk around the old town area. If you like, go into the fort ( the Citadel) where you have great views of the river, and that beautiful hotel.

第四日：Montreal开回Toronto， 计划去游Thousand Island
You can park your car at that International bridge, and walk to the highest point of the bridge and feel the thrill when the trucks pass by. and, have a great view. You can also take a cruise tour; remember to take cruise that is close to this bridge which is in the middle of the islands. If you take a cruise from Kingston, the first 2 hours has nothing to see at all.
