first off the WSOP'rs will be long gone and forgotten in Vegas at this time,
Ok, here's the rub, dependent on what you want out of it
It does really help to know where you are from, but in retrospect if its outside the (my) BIG 5 (California, Nevada,
New Jersey, Florida, or
Michigan - which I am guess it is none of these) it doesnt really matter much.
If you just want good, easy, very profitable poker then may I suggest going to Tampa. There are a ton of card rooms there that have BAD BAD BAD players, the weather will be awesome, and it will be high tourist season. The poker rooms are nice and its my personal favorite place in Florida (top 3 in the country btw - for me, the Disc Golf is to die for!)
If you want an experience, then go to Vegas. The weather will be nice, lots of tourists, but the poker will be pretty slow, especially for tourneys (outside Aria and The Orleans) for buy ins under $200 that actually have structure (and prize pool) that wont make you puke, however its still Vegas - and as my good friend Mr. N Flanders says "the lights, the sounds, the letter x, its all designed to inflame the senses".
Except to go see the River Walk I would never go to AC for anything unless someone paid me a shit ton of money. the poker is fair to good, a little history, but all-in-all a dumpy version of Vegas.
California has a lot of great poker, it has Hollywood, its freaking L.A.! But damn expensive to visit, let alone live there. May be worth it though, you will see tons of pros at the poker rooms there. PLUS the WSOP circuit will be there at the Bike
