“Anywhere!” I think it really depends on what you like to do when you’re on vacation at that age. When my child was 12 months, she loved colorful gardens, open grassy areas, and twinkly lights after dark (think Christmas lights, that are also at large amusement parks). She also loved crowd watching and would happily sit through semi-long theater performances (60 to 90 minutes). My particular child didn’t care for long walks in the stroller at that age (preferred to walk herself or be carried) so I went places that had plenty of benches / chairs for me! : )
