Are BJJ open mats in Sunnyvale open to visitors?
Not always. A gym can welcome class drop-ins and keep open mat members-only. OpenMapp stores those as two fields. Never assume a listed open-mat time means walk-ins are welcome — check the gym card.
Are BJJ open mats free?
Sometimes. Some gyms list a visitor drop-in or day-pass price; some list $0; some do not publish a visitor price. OpenMapp only shows a fee when it is a published visitor drop-in or day pass — not a trial or membership. If the card says unknown, we do not invent a number.
What is the difference between an open mat and a class drop-in?
A class drop-in is a taught session. An open mat is rolling time with little or no formal instruction. Policies are often separate. See OpenMapp’s open mat vs class drop-in guide for how the two fields are labeled.
