We will be driving down to Cornwall (from Manchester area and staying around St Ives area (with DC and DDog). Trying to figure out how to fit in a trip to the Eden Project. We won't get to Cornwall until evening if the first day and will be putting DDog into Day Care for one day whilst we are away but see that it's around a 2.5 hour trip from St Ives to Eden project. So, need to drop DDog off at around 7.45am and then drive to Eden Project.... need to pick DDog up at 7pm. Is this trip worth doing? I don't know what traffic is generally like in that area and how long this trip and look around EP will take. Any suggestions, advice appreciated.
