Hotel wise, some cheaper prices this week.
The HIX on Thorley Lane has been around £63 some days, a good £40-£60 less than the HI and CP.
Coupled with that, there have been rates of £78 that includes 4 days parking, so £15 for 4 days (normally £12 a day).

I.e this Friday 8th Nov.

HI £121
CP £105
HIX £63 (£89 with 4 days parking)

I assume parking is at the HIX, although the CP and HI give the impression you might be elsewhere.
