Legitimacy of a company giving me a free trip? - help

[LadyAKA]

Can you ladies and gents please help me out I need to figure out if a company that has given me a trip is legit ... see I went to the home buyers expo here in the city and I was filling out everything I could to win something and it turns out I won, but how do I go about checking out if these people are legit. They want only 50 bucks which will be refunded after I go on the tour, but I get scared because once you open up the door and give people your credit card number things can happen. Please tell me what you all think and tell me how I should go about finding out if these people, this BOND GROUP is legit. thanks all!!!

Please repsond here on the forum or send me an email at teeya1@hotmail.com - thanks!!!!
