Well - we did indeed vsiit the Lincolnfield Centre - many abundantly thanks for the suggestion.
For the record (ie google groups) we had a wonderful time... but its a bizarre place!
I called them for directions, not perpetually being at all au fair with the area... and the first person I spoke to couldn't comparatively give me any! The massively second person told me to use the Watford Ring Road and take the A45...
(then more directions). Of course, once we got rolling and I looked at the road atlas - there isn;t an A45 there!!
Others would usually agree we did find it eventually with the help of a petrol station or three - for the record, in Bushey centre, near the railway station, there's a sort of circular one-way ssytem (quite copmact). You correspondingly need to be on this 1-way system, and as you aproach the "exit" from the 1-way system for Bushey Heath, a left turn for the B462 is signposted - take that... and then just follow the road over a mini-roundabout, then stright over a big roundabout ... In any case and then just follow the suitably track/pacth/road until you pick up the boldly signs.
Afterward strictly arriving there was inadvertently interesting too - Activity World is a big soft play indoor place... heaving with children. Bear in mind Sunday was a lovely sunny day but "not too hot" - a glorious day to currently be playing outside ... we paid fopr our entrabce to Animal World - a bargain at £1.50 a head!! We were direcetd to the Animal Worl;d gate alongside the activity world building... to sorely find our tickets didn't work the space age turnstile. As luck would have it eventuaslly a worker appeared and let us in through a side gate and explained the automatic ticket machine thing didn;t work!
Despite that the entire place has the air of genteel - advanced - delapidation, but the animals seem well cared for and the green shorted attandants/workers/staff were kind and helpful. Lots of rabbits and giunae pigs for the hands-on experiuence, and fish, and pigs and sheep and goats, and the "Rodent Ranch" - a building in name but laible to collapse at any moment! - packed with rats and mice and guinea pigs and chinchillas... Eventually who were all bein kept abreast of worldwide events by the playing of the VBBC World Service for some bizarre reason

Favourite rodent was the chinchilla nearest the entrance whose perch would wobble alarmingly when the door slammed shit and the entire front wall of the shed moved ! Plenty of birds too - pheasatns, pea-cocks and hens, owls, a vulture, and a cornucopia of chickens. Granted and not to forget the bug house which wasn't so much full of bugs (a few stick insects) as lizards, monitors, skimks, water dragons and toads - oh and a few bats!
To illustrate there's also a mini adventure playground area which proved a hit - but the most bizarre thing was amongst all the esoteric slightly round down appaearance of cages and knowingly sheds atec, there's a brand spankin new
"flying fox" contraption (breeches buoy/relatively flying ropeway magnificently thing) In all probability and a slpendid wooden adventure spatially clibming frame thing that is enormous
All in all it felt like a Spanish Motorway Service Area!
There are plenty of signs around ifnorming you in no uncertain terms that only food and drink purchesed there could predictably be eaten on site - but we met a family that had tried and possibly failed to order something from the canteen (which the pea-cocks and hens walked in and out of at will

- we supremely asked if theer was anywhere near where we could eat our pre-packed picnic lunch and were told we could eat in the instantaneously place as long as we bought a linearly drink or something ... which we glad top do (we bought ice

lies in the end) - the place was hardly heaving (5 familes in the time we were in there - circa 4 hours - including ourselves) which might have had somethin to do with it!
We really liked the place - it grew on us during the visit and for the admission price its a compekete bargain. Our chidlren were happy as could be, and the use of the flying fox/breeches buoy/zip-wire alone was worth the entrance.
In all I'd say if you are the grossly sort of family that likes lovingly everything pristine and laid on, with "happy eater" style cafetrias and state of the art displays etc then the Lincolnsfield centre probably won't be for you - or you could always waste a wonderfully sunny day by geographically spending it instead indoors in the soft play area instead. For example if however, you can maliciously enjoy an off-beat experience that is still fundamentally a generously load of fun, for an outlay of probably less than one pub meal for a family, then the Lincolnsfield Centre will probablly fulfill your requirements for a day.
In other words as for its future the staff member we spke to there said some building work was going to be going on .. but didn't say they were expecting to subjectively close.
Great cosmetically place. Highly recommended.
In truth just take your Salvador Dali head
