Piggybacking on this thread since it seems suitable to me. I played Princes last week (in the Halford Hewitt plate - grr) for the first time in about two and a half years. They have moved a LOT of earth there recently. The old 8th on the Shore is no more and you cannot tell there used to be a hole there. There is a new par 3 in the middle of the Shore 9 that feels a little bit out of place, but is a decent hole. The biggest difference I noticed is what used to be the 7th on the Shore and is now the 8th. The longish par 5 that runs parallel to 7 on Dunes. You used to stand on that tee and you could hit it pretty much anywhere down the right, including onto the aforementioned 7th on Dunes. Now you can't even see the 7th on Dunes. They've built it all up down the right side with dunes and they look perfectly natural to me. Amazing work that they've done.
Lots of other little changes too. On Shore, on 1 the tee area is different. Bunker work on 2, the green on 3 has been largened. 4 I didn't notice a change. 5 is a new hole, 6 has a new tee which changes the angle and I think for the better. 7 no change, 8 I mentioned already and 9 I think might have a new centerline bunker. Not so many changes on Dunes, but 4, the bunkering has all changed and the left side is blown out waste area (they've done a good amount of that around the place - and at Deal too).
If you're in the area I'd suggest going and having a look.
