Well, tis the season to go shopping it seems.
Edinburgh is jam packed with people in the town center. I read that the official Christmas Market on Princes Street is unbearably busy, with some people turning around and walking away because of the queues. Even outside the main areas things are busy, especially at weekends. Luckily, I'm an early bird so, if I need to go near the epicentre, I can mostly avoid the crush. I assume it will be getting worse.
It's definitely something to take in at night though. I like this time of year because of the number of things to do but I prefer the smaller and less commercial attractions. Some reports to come hopefully.
