In some of the reviews I've read, people have stated that many passengers on the bus to El Portillo got motion sickness because of the ups and downs and such on the long bus ride to the resort. Now that they have the new toll road which it sounds like most (Canadian) carriers use, is it a much easer ride in? I know the travel time is cut in half, but not sure if it is just generally a smoother ride so less likelyhood of motion sickness. Both myself and my son might be a bit prone to that extreme bus ride so I just want to see what that new toll road is really like. And can anyone confirm that all Canadian carriers use the toll road (Westjet, Air Canada, Sunwing, AirTransat/Canjet)?
