How about a small cooler?...................![]()

you could lay there like a slug and not have to keep going back to room to get another road soda
I also bet I could "insulate" my wife's purse or a beach bag (that you normally stuff towels and beach stuff into) sufficiently to carry a good number of beverages down. Then just discreetly refill the road soda cup as needed....
You're overthinking this. A $2 plastic reusable starbux cup (everyone drinks starbies) with your softsided cooler and you will be fine. Any other clear resort issued cup is ok too (no red solos). Just be discreet (not secretive).
Someone above said no coolers though, hence my thoughts on an insulated purse or beach bag.
