Been for 4 days at the Fringe most years since 2014, this is my specialist subject!
You’ll be very very lucky getting decent accommodation within a reasonable distance at this point. Especially for that long. We got priced out of central hotels (this year the travel lodge hit £1000 for 3 nights) so we now stay further out in Air BnBs we book the day we get back the year before. Get the most choice and for a less than the price of a central hotel.
Also: 7 days is a lot. Pace yourselves, it’s very intense and crowded especially in the old town. Plan for a few hours out of town a couple of times during your stay. It’s why we go for 4 / 3.5 days - it’s enough.
Be prepared to spend. Shows are eye watering prices this year, and most are just an hour. Book any you deffo want to see in advance and download the tickets to your phone so they’re offline, the crowds mean phone signal can fail in some areas.
Check the location of venues when booking, I cannot emphasise that enough. Leave at least an hour between shows. If time between shows is a factor, plan your route. Learn from my experience! 😅
Don’t bother seeing any acts who’ve been on TV, they tour all the time. Take a chance on something random! If you walk past a long queue, ask what’s on and consider trying that the day after, for example.
Talk to people in queues, ask what they’ve seen. Word of mouth is king. If you find something you like, look them up and see who they might be compared to - join the dots between acts.
Also the Free Fringe is brilliant, where you put money in a bucket at the end. Don’t rule that out, some of the best acts I’ve seen have been free. But as they’re non-ticketed they might fill up! You might queue and not get in, so consider a back-up just in case.
I could go on!
