Arena Ticket Question

Good evening fellow Downloaders!

I have a couple of questions, the first of which MAY have already been answered (if so I apologise!)

1. I have a weekend arena ticket, but will be staying at a hotel nearby. Once I’m in the arena, am I allowed to come and go if I need to go off site to get anything?

2. Apparently the festival puts on a bus for the hotel I’m staying at (East Midlands Holiday Inn Express). Does anyone have any info about if it’s just the one per day, if I need to pay to use it etc? Any info would be hugely appreciated!

If anyone’s staying at that hotel, I’ll be there from the Monday so if anyone fancies meeting up for a drink, let me know!
