I used the free WIFI at the pool last week - I loved it!
There's a huge area with tables and umbrellas next to the pool lounge/snack bar. Very comfortable and private. The bar opens at 10 am and they have coffee, cocktails, snacks, etc. Nice music too.
I will have no problem using this during the convention....plus the pool area is open 24 hours (don't try any hanky-panky, security watches the pool area after the lifeguard leaves like a hawk! )
