Well, I'm off there for the June Bank Holiday (Harvey's Point) and really looking forward to it- though it was reasobnable, btw I could have one or two nights or any combination there of. Also no 'premuim' (having to book extra nights, extra on the room rates) one also associates with bank holidays.
Still think it's scandolous that you have to book two nights when you only want one - I for one wouldn't even entertain a hotel that suggests that. Pure greed, even if it is in their terms and conditions....
