To book or not to book

It’s always been a bucket list item for me. A Eurovision event. Missed it twice in the UK. But secretly it did have to be a bucket item, but in a different country. Never been to Austria Vienna, so gonna grab the bull by the horns, and book now, catch cheap rates. £600 for a week inc flights. Near the town hall. I do want tickets for the sat night, but too early for that. But definitely more than happy for the street parties, just wanna be with the vibe. Any do’s and dont for it all, before I go booking stuff
