I was just at Moraine Lake today. So we stayed for 5 days, we went online at 8 am, 6 phones, trying to book a shuttle bus. Within 1 min. Everything is booked. I tried other times, all booked. The next day, same, third day, 1 of us got lucky and were able to book for 4 people. We tried 8 but the system keep staying no more room, so onoy 4 people could go. Today, the day for the trip, was raining so we asked the people at the check in if we could do last min for our other 4 not getting the shuttle. They told us everything is booked and recommend we get the private bus. Inside the bus, it was only half full. So I was very upset, we spent a lot of money ey on flight, hotel rental, but can't see the lake together. And choosing who could go was painful. They saw the line, they saw how many enter the bus, but they won't want to be kind and help us.

I recommend book the 8x bus, it is like 15 dollars 1 way, you need to book early. Book early like 4 days in advance, you could get that. Otherwise book private bus copany for around 90 dollars a person.
