Hotel rooms can be tiny or roomy. A basic room has a bed, a sink and a bathroom nearby, while a suite usually has extra space, sometimes a small kitchen and a private bathroom called an en-suite. Hotels label rooms with numbers or names so guests can find them easily. Bigger hotels add many services: a concierge helps you plan trips, room service brings food, and there can be restaurants, pools, gyms, and business centers. Economy hotels often offer a simple breakfast. Some special places include capsule hotels—tiny sleeping pods—and glass igloos where you can watch the sky from bed.
