Just got the same call and was tild the same exact thing have you heard anything else?

There appears to be no business called "Grand Travel" in Tampa. There is a travel agency called "Premium Destinations" at the address you give. They have 13 reviews listed on Google, several of which are rather suspicious-looking 5-star reviews. They are outnumbered by the 1-star reviews, which include this one:
"We were sitting on the beach at Daytona when we were approached by a lady who promised $50 in cash, a free 7-day vacation and $100 for dinners at places like Olive Garden and Red Lobster if we sat in on a 90 minute promotion. She didn't tell us what the 90 minute promotion was about but it had something to do with vacations. We agreed to go but had to give her $20 to hold our "reservations" for the 90 minute talk. She said we would get that back when we arrived at the place where the talk was given. We agreed and gave her $20. We went to the 90 minute talk. We received a reward credit card for $70 (the $50 plus our original $20). The 7 day free vacation was a scam. It required us to send in $100 and then it would still not be assured because the dates were not all available. The free food at restaurants were coupons that we had to search online. We had to pay $25 to get $10 or $15 off the total price of the meal. The restaurants were awful. Places we would never go to. This was a waste of time!
