We really enjoyed our trip to the Eden project, we pre-booked an advanced family pass online which allows us unlimited entries now for a year (great for half terms etc). It was lovely to go into the rainforest biome and feel the warmth in the British winter time! My eldest son has asthma and it was nice for him as his chest gets tight in the chilly weather. The only downside was that after paying quite alot for our pass, the ice skating was extra cost, especially as we live in Cornwall. I would also recommend bringing snacks and sandwiches/drinks in a backpack as the restaurant area gets very busy at lunchtime and there's nowhere to sit. We did however grab some ice cream from a stall upstairs which was really nice!
