What is the best way to set up my Calendar availability to avoid having long gaps in my day, while being available to clients?
The best way to do this is to start with a two hour available window on your available days. Then once you've got your first booking for the day, reduce the hours to show you are only available on times directly adjacent to the booked class. As the adjacent hours fill up, continue to add available hours and grow a multi-hour day with no gaps. If you travel between client locations, it is recommended to block ~15-30 min between lessons to allow you time to clean up, give feedback, use the bathroom, have a snack etc. and arrive on time for your next class.
