Startpoint Resorts in Vegas Nevada review: Timeshare

Me and my girlfriend went to Vegas for some first time fun time, while there we ran into a person who offer free bees to the strip area for a 90min presentation which turn to almost 3hrs.
I was mislead to believe I can use this great deal of timeshare purchase to make family memories for a great deal thru their resorts

Turns out I can't cancel it according to them and as well I came to find out
Time share is available on eBay for pennies on the dollar compared to what I paid not including these maintenance fees that I can't get rid off for the next 45years which means if I pass away my kids will be stuck paying for this without them even having a choice on the matter, I can keep going on what this scam of a business this is but would just like some help to get out of this financial mistake I made by being taken advantage from!

I would love some help from any one who has gone thru this or can professionally help as I'm not gonna be able to afford to keep paying for something I will never even get a chance of using

Thanks in advance to anyone out there willing to help
