Going to book my first experience day in the next week, I was looking at the Cheshire centre or eastnor, has anyone done both & if so what's your thoughts?

I haven't done the Cheshire one but have done Eastnor, it is certainly worth the longer trip and paying the additional fee to upgrade to the full day. Dunkeld is pretty good too 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced
2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Done both, but Eastnor is better imo as it is more extensive and rather more challenging especially in mid Winter. Cheshire (Peckforton) is pleasant plus there is a nice inn - The Pheasant at Burwardsley not far away with great views over the Cheshire Plain which is dog friendly also.

I've only been to the centres Peckforton Castle (Cheshire) and Coniston Hall (North Yorkshire) in the past so cannot comment on Eastnor. My experience at Peckforton was far less 'hands on' than at Coniston (which may have been down to the individual instructor on the day). My driving experience was limited to a few muddy tracks - not especially challenging - with the instructor doing the more interesting stuff. By contrast Coniston was 'hands on' all the way and much more enjoyable!!
The views across the Cheshire plain were pretty though..........

Lode Lane is worth considering, however the best has to be Eastnor. You will note on part of the Eastnor course a couple of closed 5 bar gates, this for the proper off road test/development, it is where Land Rover test vehicles themselves.  In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures
Gone - A couple of RRS, A couple of Disco's. However thinking of another Sport.
