we're going to sherwood in four weeks - we'll be taking with us as definately required:
bike padlocks
torch - it gets v.dark at ngt
all our food - v.expensive in onsite supermarket - we won't be eating out.
bikes - i think are £30 / weekend - you get one with a back seat thingy for little ones
pool is quieter late pm and evening
spas/sauna etc are v.exp in relation to local gym
ten pin bowling is exp but one of few evening activities.
childrens disco free, plus indoor and outdoor play areas.
take a few toys for villa
oh, you have to pay to choose your villa, so go with the flow the first time and suss out whether the whole cp thingy is for you then you canrebook safe in the knowledge.
at sherwood we like to be out on the outskirts by a lake but at elevden preferred being a little closer to centre.
if you do longleat - the safari p[ark is next door and well worth a visit - would go there before check in and then on check out day - one ticket price lasts a year!
you get all the booking extra activitites stuff two weeks before you go so can plan ahead and i think prebook - last time I went 10yrs ago - we had to send dad out at 8am to queue in the centre to book that days activity, knowing we might not get it and end up playing some obscure, never heard of sport.
this is all a bit long but hopefully will help. there's a couple of threads in archives I read before we booked this time as it'll be our first trip with the dd's and was looking for tips.
