BEYOND its tourist attractiveness, Valley Forge draws enough conventions and business conferences to keep half a dozen major hotels and a swarm of motels busy. In fact, according to tourist industry sources, the occupancy rate of its 5,000 first-class rooms approaches 100 percent during the season from Memorial Day to Labor Day, and stays in the mid-ys the year around.

But the innkeepers are not as busy as they'd like to be on winter weekends, so most offer getaway package rates that are yet another reason for a cold-weather visit.

The easiest way to get good advice and detailed information about lodging -- or just about anything else -- in the Valley Forge area is to call the good folks at the Valley Forge Country Convention and Visitors Bureau (800/458-6000). If you're planning a future visit, they'll load you up with brochures; if you're heading up to Pennsylvania right now, they'll make your reservations.

One favorite getaway place, even for local residents, is the the Sheraton Valley Forge Hotel with its fantasy rooms and suites. There are about five dozen of them, priced from $125 to $175 a day (but check for special rates). Each is decorated to a theme such as Tahiti, the Commodore's Cabin, the O.K. Corral, the Costa del Sol, Victoria's Parlor and Samurai, and there are guests, the hotel says, who are working their way through the whole lineup at the rate of three or four weekends a year.

All the themed suites and rooms have whirlpool baths plus some such special features as waterbeds, saunas, hot tubs, lofts, flying beds or private elevators, all designed to cater to the sybarite in you and your Significant Other(s). If you ever manage to pull yourself away and venture outside, you'll find yourself right at the park entrance. SHERATON VALLEY FORGE HOTEL -- Route 363 at First Avenue, King of Prussia. $90-$175. Sixteen floors, 330 units, racquet club and spa, barber/beauty shop, game room, three restaurants, nightclub and delicatessen. 800/325-03535. The newest major hotel in the area is the Embassy Suites, which opened last fall. All the rooms are suites with (at least) a separate living room, a wet bar with refrigerator, telephones everywhere, including the bathroom, and two remote-control color televisions (but with indifferent reception of only four channels). The suites are ranged along balconies overlooking a vast atrium.

It's all quite attractive, but there are curious lapses in both design and execution. The worst is the apparent total lack of sound insulation: I came away intimately familiar with my next- door neighbor's problems with his boss, his wife and Somebody Else, and was entertained at length and against my will one night by a singer in the atrium several stories below. And while the maids are so eager to clean the rooms that one of them knocked steadily at my door throughout my morning shower, the air filter in the heat pump was so heavily clogged that little dust devils erupted every time the thing started up.

On the other hand, Embassy Suites has an attentive staff, excellent room service, free full breakfasts and complimentary cocktails from 5 to 7 p.m. They also like children (even room service has a children's menu) and they offer weekend getaways at $89 per couple per night.
