Back at work now. Holiday over. We had a super trip. This is how it went:
1 night in Treviso (Near airport as flight was landing at 10pm)
1 night in Venice - 2 days walking around, expensive, but a must see.
1 night in Verona - Lovely spot. Wanted to stay longer.
2 nights in Sirmione (lake Garda) - 2 days relaxing by the pool + lake
1 night in Florence - Not great. Queues to see David were huge, so skipped it
2 nights in Pisa - Enjoyed this stopover. Needed the reast after all the driving.
3 nights in Rome. Super city. Enjoyed the Vatican City, Catacombs, roman forum.
For the diving we borrowed a Sat Nav device. Have since bought one for myself. Saved a lot of hassle. Just punch in the address of your hotle in the next city - hit the GO button - off you go.
