Italy very hot in June/July
We took rainydays advice form the start of the thread and opted for Italy as our destination. Only about a two hour flight to Rome, so we weren't over tired from the trip. As suggested we were exhausted after all the festivities.
We stayed in Rome for 3 days, then went to Sorrento for 10 days, before going to Milan for three days then home.
If we were to do it again, we would just go straight to Sorrento and stay there for the duration. Rome and Milan were great, but there was too much hassle moving around between cities, One venue would have been more relaxing.
We travelled to Rome at the end of June and temperatures were tipping 40 Centigrade, although it must be said the sites are worth seeing, even if it is stifling and watch out for the scooters !!
Sorrento is fabulous as is the whole Amalfi area, at least when we got there, we had the swimming pool for refuge from the heat
I would say Milan is a great city for the less financially challenged, but we enjoyed browsing around Emporio Armani et al.
We will certainly be back in Sorrento, but alas we neglected to toss a coin in the Trevi fountaion, so probably not Rome again
