2. Trinity College in Dublin doubles as a hotel

If you plan far enough in advance, you can stay at historic Trinity College while you’re in Dublin rather than staying in a hotel. The reservations fill up quickly because of their location and because they’re relatively well-priced. The accommodations resemble small dorm rooms (some arranged like full apartments). You’ll spend time on the grounds where iconic graduates such as Oscar Wilde, Jonathan Swift, and Samuel Beckett lived and studied. Plus it’s smack in the middle of downtown and within easy walking distance to just about everything. Trinity College is home to the Book of Kells and to the famous Trinity Library Long Room, both must-sees for anyone visiting Dublin.
