Futures Parlay in Vegas

I'm heading out in a couple of days and know that 5dimes lets me do this, but is there a book in Vegas that allows you to parlay futures?

If there is a line up there or posted on the worksheets off to the side (season win total, odds to win the superbowl, first week NFL games, etc.) then yes, you can bet any parley you want.  If you win, there are instructions on the back of each ticket that tell you how to mail the ticket in to redeem your winnings

Not at the three books I use. I use William Hill(which you definitely can not parlay futures) and every once in the while I will roll into a station casino or a coast property and they never used to allow it before.
