If you're trying to get in the Ibis Budget and they say it's full on the Friday night, it isn't! They're holding room back from their website and their reservation system for some reason. I rang last night and they said there are still rooms available but they are not showing them.
Their reservation staff will just read what showing available on their system so ask them the double check with their front desk or manager.
Rooms on flexi-rate: £79 for the Friday, £59 for the Saturday.
