# What is Self-Service

Anytime you want to use a SixFour3 facility to work out on your own, that is classified as "self-service" (versus an "Instructor-Led" service with one of our [SixFour3 instructors](http://www.sixfour3.com/trainers)). With standard memberships, you have up to 16 30-minute slots over the course of your monthly term (limited to 2 hours of booking per week and 2 hours per day). With the PLUS+ add-on, you have 48 30-minute slots for your term (limited to 6 hours of booking per week and 2 hours per day). Each slot is booked in 30-minute increments and can be sequenced together however you see fit. For example, if you want 60-minutes, you would book two connected times together.

**Note: During [peak hours](https://help.sixfour3.com/article/18-what-are-peak-hours) self-service time may be limited, at our discretion, to help ensure maximum availability for all members.**
