Bringing Cash to Vegas

I am travelling to Vegas this weekend, and this will be the first time that I am bringing a large sum of money to play with (large to me, at least... $5K+). What's the best way for me to do this (assuming the best way is NOT to lug a wad of cash in my suitcase)? Traveller's checks? Set up a line of credit someplace in advance?

Odd (possibly dumb) question, but something I've never addressed before.

Thanks in advance.
