Slovenia's biggest thermal resort is the affordable sleeper hit of this list: a dozen outdoor pools fed by warm springs, wave pools, pirate-ship play islands and slow rivers, plus indoor thermal pools that keep the whole operation running in winter. Families stay in the on-site apartments, mobile homes or an actual Indian village of teepees. Prices are a fraction of western Europe's, and Zagreb airport is only forty minutes away.
