They advise against leaving the room. It can make you feel worse and possibly pass out. Its better to lie down and relax until the dizziness goes away. Which people do all the time. They will even give you Pedialyte if necessary.
Absolutely. This studio is quite relaxed in that regard; from the classes I've been to no one would say a thing (I'd just try to do it as quietly/discreetly as possible, depending on the noise level of the room).
