Atlantic City is always reinventing itself. This summer, the casinos are adding new touches to their fantasy playgrounds.

Try a “dive-in” movie at Harrah’s (www.harrahs.com). They just opened the city’s largest indoor pool, part of a brand new, quarter-acre domed entertainment oasis.

Besides the 23,000 square-foot pool surrounded by a million dollar garden, there’s a new Red Door Spa (www.reddoorspas.com) with 23 rooms, including a couple’s suite (steam showers, Jacuzzi, and fireplace) just in time to put on your Father’s Day gift list.

Over at Caesars, (www.caesars.com) they’ve amped up the volume at the Circus Maxiumus Theatre with a new million dollar sound system and a new layout for the 1,500 plush seats. American Idol star Carrie Underwood was the inaugural act last weekend.

Our readers already know about the Pier at Caesars (www.pieratcaesars.com), because we’ve been raving about it for months! NJ Monthly’s empress of good taste Rosalie Saferstein likes breakfast at Sonsie (www.sonsieac.com). We liked the shopping on the huge enclosed pier, and lunch at Buddakhan (www.buddakanac.com).

Not to be out-trumped, the Donald’s Taj Majal (www.trumptaj.com) has eateries serving frozen cocktails, burgers and candy lining the streets of the new Spice Road Promenade. At Trump Marina, (www.trumpmarina.com) we hear the new Finestra Restaurant has an awesome antipasto bar.

And this month, the AC version of the New York Providence Lounge (www.providencenyc.com) opens in the red hot Quarter at the Tropicana (www.tropicana.net). Bottle service, DJs and VIP rooms.

Plenty more to come, as hotels and casinos add, improve, and grow—all in an effort to keep you longer, and get you to spend more. This you can bet the house on.
