Scheduled to Attend in March? Do we Go?

Hello,
I attended the Trump session of people selling ideas and ways to
become wealthy. My sister and I signed up for the Real Estate 3 day
course offered by James Smith. I usually do NOT spend that much money
just off the bat..I have learned from my father not to rush into
things...however, hopefully not sad to say, I did. So now we are
scheduled to attend Feb. 27-Mar 1, 2006 in Las Vegas. I had a bad
feeling about this the next day, but my sister wants to go. I don't
want to spend the $3,000 if I am not going to benefit from it. Nor, as
I have been reading, if I will be pressured to spend more on a 5 day
class.
I really need people to respond back on weather they felt it was
worth it or not, please help.

Thank you!
Ann
