When DH and I were in our 50s, we twice went away with Lochs & Glens, once to Loch Awe and the other to Loch Lomond. Both trips were brilliant, the coach drivers knowledgeable and friendly. The hotels were lovely too. The only minus was sitting in the dining room with another couple, who were perfectly friendly, but I don't really do small talk, so found it a struggle. Would definitely recommend the company though
