Accommodation
There's a pretty good range of accommodation all over Scotland: from bohemian hostels to ritzy luxury lodgings.
But unless the point of your trip is to indulge yourself in luxury, or meet like-minded folk at hostels, then you're usually best making accommodation a secondary concern. Choose where you want to go first, then hunt online for a place to stay.
Hotels & BnB’s
As you'd expect, the biggest, most popular cities have the best selection of hotels. In more remote locations, the standard form of mid-range accommodation is the Bed and Breakfast, and often in short supply at peak times. You may have to take what you can get, but most are nice enough. Scottish B&B’s tend to range from one to half-a-dozen rooms in the host’s house and have an equivalent status to North-American motels (rather than the generally high-end boutique status of B&B’s in North America), though of course they’re far less anonymous. Breakfast almost always means a full cooked breakfast, if you want it, as well as cereals and toast, all of which should set you up for the best part of the day!
