My husband and I are planning a 14 day (flexible.. could stretch to 3 weeks)trip to Scotland (my heritage) and Ireland (his heritage). We want to include the Royal Tatoo in our plans, but other than that would really appreciate some expert advice on 'must sees' and a suggested itinerary. We have not been to England, but thought we'd save that for another trip... is this good thinking? We love travelling by train and are nervous about driving in Ireland. We hear Scotland is easier to drive. Our friends recommended RS tours... but we don't see a combined Ireland/ Scotland tour... is there a reason why we should know about? Thanks for any help.
