Recommend flying into Edinburgh and spending a couple days there either before or after the wedding – there's plenty to do in Edinburgh, including visiting Edinburgh Castle, Arthur’s Seat, the Royal Mile, the Palace of Holyroodhouse, Princes Street Gardens, shopping and excellent restaurants!
Take a day trip to nearby St. Andrews, Crail, and/or Anstruther (be sure to get fish & chips at Anstruther Fish Bar!)
Visit the Scottish Highlands - Home to hairy Highland coos, Loch Ness, Eilean Donan Castle, Fort William (Ben Nevis), Jacobite Steam Train, Dornoch, Faerie Glens, the colorful harbor of Portree, and so much more!!
Visit Glasgow - home to the Scottish Opera, Scottish Ballet and National Theatre of Scotland, as well as acclaimed museums and a thriving music scene.
