A throwback to the glory days of heart-shaped bathtubs and gaudy theme decor, the mid-range Cove Haven Resort is a couples-only property stuck in the summer of love in the Poconos. A honeymoon destination since the 1960s, this Poconos getaway has become an American institution whose founder invented the heart-shaped Sweetheart Tub. Nostalgic couples can immerse themselves in a fantasy of giant Champagne glass-shaped whirlpools and choose all-inclusive packages, though many find food mostly uninspired. Most guests will also find cleanliness lacking even if they appreciate the aging decor. There's plenty to do indoors and outdoors year-round -- including boating on Lake Wallenpaupack and snow tubing -- but the hotel is definitely pricey for what it is and in need of renovations. Couples seeking something less themed may want to compare rates at the Mohegan Sun Pocono.
