I would want all the protections I can get when dealing with merchants that aren't known for the best customer service, especially during the havoc of CES week. I ended up booking using my United Mileage card.
If you're worried about some sort of billing mixup, Amex and Chase are good.
But purchase protections are usually more about stuff breaking or not being as described. If a flight is late, travel delay insurance may be helpful, but new Platinum accounts lack it (IMO, the card's biggest flaw). If a hotel room is disgusting, I'm not really sure what "protection" a CC might offer as long as you got the room type for which you paid.
