Me and DH loved the Eden Project. A day there was no where near enough time so we would love to go back.
We both love France and have visited quite a bit of it. Not keen on Paris though. We have been 3 times because we kept thinking we had been to the wrong bits! Avignon is lovely though and we both love Mont St Michel. Driving to it, its looks like a fairytale castle.
Amsterdam is ok but much prefer other places in Holland. The Hague, Delft, Utrecht, Haarlem are all nice and we both absolutely love Leiden. We both say we would love to live there. Visited about 5 times so far.
Really like Belgium. The coast is nice and the tram, as another poster said, is great. Means you can travel all along the coast without needing to use the car. Very cheap too.
Went to Brussels for the first time this year and was wondering if we would like it due to the negative comments it gets on mn. We both loved it. Spent 3 days there but nowhere near long enough so will be going back. Ghent is great too.
Loved Stockholm and Sweden in general. Would love to go back but so expensive so not sure we will.
We went to Prague in 1995 and absolutely loved it. Went back in 2004 and it was nowhere near as nice.
Haven't been to Blackpool for years but used to like it. Yes it was tacky but we expected that.
Only place we have been that we were not keen on was Glasgow. That was probably due to the horrendous weather - 3 days of non stop torrential rain - and the rude, useless taxi drivers though. When we got to the airport to come home they said our flight might be cancelled because it was so windy. I burst into tears at the thought of having to stay longer. Thankfully the flight did go ahead but 4 hours late
