It looks like I’m not going to see Amenra in Antwerp in July.
I think today is the first day I can book the Eurostar for the dates and that comes to £104 return, which is fine. However a quick look at hotels shows that everything is £750 for three nights and Airbnb is £500 for something shit to £1100 for fairly central 
I don’t know what’s going on but I think I can spend that kind of money better eleswhere.
