Is Temple Bar worth the money?

It is worth walking through for the photos, but avoid buying drinks there. You will pay a premium for the atmosphere; walk five minutes in any direction to save 40% on your pint.

Should I buy a Dublin Pass?

Only if you plan on visiting at least three 'paid' major attractions per day. If you prefer walking and free museums, the pass will be a waste of money.

How to Visit Dublin on a Budget

Skip the pricey hotel district of Temple Bar and stay in Northside neighborhoods like Smithfield. Prioritize Dublin’s excellent free museums and walk the city instead of relying on taxis to keep daily costs under $120.

Use public transport from the airport. Do not take a taxi. The Dublin Express bus or the Aircoach will get you to the city center for roughly €8-€10. If you are staying near a Luas line, take the 41 or 16 bus for even less, though it takes longer.
Buy a Leap Card immediately. Pick up a Visitor Leap Card at the airport or a convenience store. It caps your daily and weekly spending on buses, trams (Luas), and commuter trains, saving you about 30% compared to cash fares.
Eat at 'carvery' pubs for lunch. Look for pubs advertising 'Carvery' lunch. You’ll get a hearty plate of roast meat, potatoes, and vegetables for €12–€15, which is significantly cheaper than a sit-down dinner.
Take advantage of free attractions. Skip the expensive private tours. The National Museum of Ireland (Archaeology and Decorative Arts), the National Gallery, and the Chester Beatty Library are all 100% free.
