It’s a big “Nope” to bring a couple of extra friends unannounced on the day of a service or experience. The host can turn them away if they’re not included in your experience reservation, or they haven’t been accounted for in your service reservation.

If there are spots available, you can add guests to your existing experience booking either before the experience starts or even while you're there. You can book and pay for up to 10 guests, but you must be one of the participants.
