Travel scam. Phony number trying to appear to be "Hilton" but wants your credit card number. Call back and they deny calling saying they don't own timeshares and the callers are imposters.
Called today at 12:45 PST, asking if I wanted a trip to Orlando and a free Royal Caribbean cruise in exchange for attending a 2 hour sales call. The woman was very friendly but refused to accept the fact that I was at work and couldn't sit there and have a conversation. I ended up having to hang up on her.
