Westin is 1 of the top hotels- their Casino is 1 of the nicest.
I stay at the Radisson for poker (Westin didnt have any last year)
The biggest (& most Action) Casinos are probably the Marriot( a 15 min walk from the Westin) & the Rennaisance 15 min by cab in the city Oranj.
If you like steak- try Texas de Brazil(our favorite dinner)
For breakfast we eat at Salt & pepper a lot
( in between Radisson & Occidental)
As you might be aware, the Westin is the southern end of Palm Beach.
Most of the Restaurants are a 5-10 min walk north.
A brand new outside mall with entertainment & many restaurants just opened a few months ago across from Playa Linda & Holiday inn
( a 10-15 min walk for you)
The pier on the water between the RIU & Radisson (5 min walk north on beach)is rocking every night for the younger crowd.
Read this forum more before you go- great info & discussion
Enjoy your trip- I'm 6 weeks behind you.
