My husband and I will be in Oban in early June for 2 nights (1 full day). I've seen so many good recommendations for the Mull/Iona/Staffa tour. If we do that, it will take the entire day we have in Oban. If we only have 1 day, is that the best way to spend it? Second question, if we do the 3-island tour, it doesn't return until 8 p.m. What are the dinner options at that point? Would we be able to easily get dinner somewhere? Also, where do people do lunch on the 3-island tour?
