Partner and I are thinking about going to Edinburgh late September/early October. We'd like to take a 1 or 2 night trip including transportation and accommodations to see Loch Ness and the countryside. Anyone know of reputable companies for something like this? We've had a couple of bad experiences with Viator and would like to avoid them. Maximum budget would be $300 per person and that's pushing it. I imagine it's better to reserve something like this in advance v. trying to arrange once we arrive? Any suggestions would be appreciated.
