Ditch the standard hotel gym and hit the historic Roman baths instead. You only need two hours here, but the 1,500 square meters of thermal pools and saunas are non-negotiable for a rainy afternoon. Heads up: the main area is strictly textile-free, so leave the swimsuit in your bag. Stick to the classic Irish-Roman circuit and skip the overpriced massage add-ons. It gets crowded on weekends, so aim for a Tuesday morning entry to actually relax.
