Did this company cold-call you? What are they promising to do for you and for how much? If you are a TS owner, what are you hoping to accomplish by using ASG? Most TUGgers have found that any company related to TSs with the word "solutions" in its name is usually a scam.
If this is an "informational meeting", what they usually do is give you some sermon about how you will never be able to get rid of your TS, MFs, possible special assessments, and other travel-related costs will increase relentlessly. As well, they will probably try to convince you that your children will inherit this financial burden and, thus, it is in your best financial interests to pay this company $3500 right now to get out of your TS.
Me, personally, I would not go. If you want to divest yourself of TS ownership, there are many helpful articles here on TUG how to do so for a lot less money if you're willing to be patient and do a little bit of work.
