I’m not sure when Thomas land officially opened as I was classed as an older child when they closed robinsons land so we never did Thomas land (until I had a baby). If you go to guest services, they have Thomas letter hunt cards. You then head into Thomas land and they have picture cards of engines with a corresponding letter that you have to find on both sides of Thomas land. Once you complete the missing word , you take the quiz card into the big Thomas land shop and they give you sweets and a sticker.
