I have seen a couple of people talk about this topic and just wanted to share our experience. We love going to the presentations, however, we are career sales people. We like to take the opportunity to look at other properties for future visits as it is not easy to hotel hop in Mexico. Also, instead of taking the promotional gifts, we ask for cash instead. Each company has a promotional spend per person, so if you would rather the cash ask for and tell them you would rather that versus the promotional gifts/excusions. They don't advertise it though as they want you to take the gifts and tours. If they make you stay after the required time, just get up and leave. You are not required to stay after the time that they told you. 90 minute, etc. We will be at SMB over Labor Day weekend and since it's such a short trip we most likely won't sign up to do any of the presentations, but usually when we are there it is for a week so we don't mind listening to what they have to say.
