It kinda depends on what entertainment you want.

It's all there. The BeachPlace complex has several loud bars, 3 drinks for the price of 1, Hooters, and more. There's live entertainment in the BP courtyard where you can sit and lick a Haegan Daz (or drink) and watch the shows. Can be noisy in the ocean front suites at BP if you're a light sleeper and if so, intracoastal view might be better -- I like the action side and with the doors closed it shuts out most of the boom boom. A boat tour of the Intracoastal is fun ... so is the Water Taxi just behind BP. Go to the 9 am Monday Morning meeting on the 19th floor for good info (they'll try to get you to take in a sales meeting so just enjoy the Krispy Kreme and coffee and get the ideas about sites).
Las Olas is great ... fun antique and clothing shops, upscale bars and restaurants, people watching - a must for one night.

On the beach strip there are some great restaurants to -- like the two in the Ritz Carlton next door and Trina's up the street at the Atlantic hotel - expensive and classy.

If you like Italian, a 15 min cab ride will take you to Primavera. Excellent.

While it was certainly neglected by the HOA, I'm pleased to say BP is currently being redecorated floor by floor and you might get to live the result -- if so take pics and tell us all about it. Ask for an updated room.
About the closest grocery store is on North Federal, about 10 min drive from BP - go once, load up, and enjoy. This is an urban beachfront part of a big city with million dollar views or one of the best FL beaches you'll find. You'll love it. Here's a view:

A cab to BP from the airport is maybe $20 or less...15 minutes. There's parking in the building if you have a car - $17 a night - but everything is so close or an inexpensive cab ride away you'll do fine without one. Fun.
