Most of the limousine operators book the limousine service or the party bus service in 1 hour increments. In Alberta for example Calgary and Edmonton, you can simply book the service for 1 hour but many people ask this question what can I do in 1 hour time?
Based on our 12-year limousine experience, we pick up most people from one location take them to a viewpoint, where you can see the city skyline take a group picture, drive them around for rest of the time when the hour is up, drop them off at the destination.
Here is an example of places to visit in Calgary if you have booked the limo for an hour https://www.ampmlimo.ca/blog/the-best-views-in-calgary
Aside from visiting the sightseeing you can also use one hour service to pick up multiple passengers from different addresses not everyone is able to meet at one spot so you can also use your time this way.
Sometimes people book 1 hour to go to the destination and then book an additional hour to come back.
Most of the major cities you can rent limousine for 1 hour, in small towns or places that are not densely populated there might be a minimum of 3 hour booking time required to reserve a limo.
