Hi Charlotte! It depends on the exact nature and severity of your friends' sensitivity, but all of the adventures do contain flashing lights in some capacity in most of the sets. These are typically very brief moments, not for more than a few seconds at a time. We have had some guests with epilepsy visit and do just fine - again, it depends on the individual - but we recommend speaking with the staff prior to entering to let them know your situation so they can advise you.
Yes they do have flashing lights. If anything I would recommend the Egyptian themed room or the castle. Just when you go double check with the staff because some things happen suddenly.
