On a budget, skip The Dublin Pass — the spend outweighs the payoff.
€75–€120+ by duration
Can genuinely save money and queue time if you're a hard-charging sightseer cramming many paid attractions into a day or two. The honest catch: so many of Dublin's best sights (the National Museum, National Gallery, Chester Beatty) are already free that the maths only works for relentless attraction-hoppers — most relaxed visitors lose money.
