Fodor's Expert Review Terme Manzi

Dating from the mid–19th century and set amid one of southern Italy's largest spas (the spot where Giuseppe Garibaldi bathed is conserved in a corner), this hotel is believed to have started the "thermal tourism" movement; as you'd expect, the decor is sybaritic, with hypercolorful mosaic columns, gilded Empire-style furniture, and lots of Las Vegas–ian glitz. The staff is ready to pamper you (and nonguests) with every kind of beauty treatment imaginable, and you can top it all off in the open-air roof pool, surrounded by Ischia's rich vegetation.
