I love to hear other opinions/experiences on different countries/cities.
We travel a lot. Overall we try to find the good everywhere we go, we have never hated anywhere we've went, but usually do our research beforehand. There are a few places we would not rush back to but nowhere I would say never again (except maybe Australia as its really very expensive and we spent a couple of months travelling so feel we have seen and done all there is to really)
We loved Paris...yes it has rubbish, we found early May this was actually not too much of a problem but I know it can be at other times of the year, I have been on a short trip with work in July and there was a notable difference in the amount of rubbish. Could it be that the tourists are the main problem? (as is the case in a lot of places) some dodgy looking characters, some rude people...but doesnt every city have these? Some really beautiful parts to Paris, great architecture, amazing food (not everywhere), some lovely and friendly people too. It had some negatives for us too but the positives outweigh them.
Perth - This was the most dull and boring city I've ever been too, WA has some great beaches but there is only so many days I can spend at another beach. Hillary boat harbour was the highlight of the trip and thats not saying much, in WA the Margaret river area and Kalbarri and Esperance national parks were good. Pretty average food the whole trip too, dressed up to look great in a lot of places but the quality was really quite poor, meat in particular (this may be down to climate difference) Very expensive to eat/drink out and for day trips (we knew this before going so we prepared but it felt a bit of a rip off really, we dont mind paying for a good experience/good quality) Had a poor experience where we needed assistance and felt people were friendly on the surface but not willing to stop to help us at all when we really needed it. Parts of the city and a suburb where we stayed with friends for a couple of nights felt very very unsafe at night. Friends lived in a nice area but youth crime was on the rise there too (apparently this is country wide not just in Perth though, we did see a lot of anti social issues in Queensland too, we did not witness anything to note in NSW) Felt WA had quite a sleazy side to it, but again found this in "most" places we visited in Australia (we spent many months travelling there so got to stay in areas a little longer than the average tourist)
Sydney - A little underwhelmed, enjoyed the opera house, enjoyed Watsons bay, loved Katoomba and the whole area around the blue mountains is really beautiful with lots to see and do, but the city itself is extremely busy, overcrowded, particularly when cruise ships dock. Found "in general" the people were quite rude and a bit miserable/uninterested in the bars and restaurants compared to other parts of Australia we have visited, we did have some great service in places though and met some lovely people (a lot of bad service was not from Australian people) we didnt have any unforgettable meals despite eating at some highly recommended spots. Felt extremely expensive to do anything, eating/drinking out was a bit of a rip off in reality, but then so was a food shop, I was suprised how expensive fresh fruit was, but this was Australia wide not just Sydney.
New Zealand was absolutely amazing and if we had the time again we would half our time in Australia and spend much longer in NZ, again it has its negatives but the positives outweigh them
