Need advise on Marriott Grande Vista-we received a postcard in the mail for 5 day/4night stay for $199 and after completion of the 90 min. sale pitch we receive $100. certicate toward theme park tix. I just found this post card as I was cleaning out some things and it has just expired...I thought about calling and seeing if they would still honor $199. I am thinking they probably would since they are looking to get families in there to buy into the vacation club, but before I do this I wanted some expert advice on this resort...we usually stay at Disney, will we be disappointed, how far from Disney, Sea World. We will also book 4 nights at a Disney resort so we will get our fix in, just don't want to stay in a dump, no matter how cheap. thanks
