We were there last week. Never been before but seemed busy to me. We stayed on the Salen Bay campsite, facilities were all open but with restrictions, you could only use the shower/toilet block with your family or on your own, no mixing of bubbles. They have canoes and paddle boards for hire and are just along from the bike hire place. I imagine they’re fully booked, about half the site had camper vans. The Spar in Salen is pretty well stocked but often had queues as did the Co-Op in Tobermory. We managed to book the aquarium easily enough and a boat trip to Staffa with Staffa Trips just a couple of days in advance. We had an excellent curry at the Cheese Barn on Thursday night, booked that a few weeks ago as they only do it once a week. Unfortunately the normal cafe wasn’t open when we went at the weekend, neither was the little cafe in Tobermory which was odd as they were open the previous Saturday. The beaches weren’t too busy if you could get parked, went paddle boarding at Calgary, Croig and Lochbuie. I think Croig was my favourite, the beach is about a 15 minute walk away.
