Back to the "Barrels", I honestly don't see the logic. It doesn't seem like many others can either. I think that they could be an alternative budget accommodation option, because there is no way that people would pay the same prices as the hotels or lodges for these small "pods". Also, the need for a separate shower and toilet building is interesting — could it mean that the pods themselves won't have these facilities? If they don't, then that's definitely another reason that these should be a budget option. As things stand there is simply no need for further accommodation, I really hope this project doesn't go ahead.
These are defiantly "budget" accommodation. The plans for Legoland Windsor show what to expect of the barrels (just for clarity these are not the AT plans).
