We attended a family wedding last year just outside Cortona in Tuscany, and as guests I thought it was excellent.
A few things though, more of the grooms family attended than was anticipated, so the 50-60 people became more like 100 (at about €80 per head for meal and wine, this was an unplanned expense). The villa for the wedding only has about 15 rooms, so others headed off to a close by hotel - this meant that the couple did a lot of to-ing and fro-ing back and forth, as none of the people in the hotel booked car hire (and the villa people ended up doing a lot of taxi-ing).
The bridal couple ended up doing a lot of the wedding co-ordination, even though they had a good planner, best man and chief bridesmaid... on the wedding day the groom was rounding up bridesmaids to get hair and make up done! And he was also co-ordinating lifts for people to the church, as the bus was full!
The service was slightly different to the Irish service, so our section managed to 'miss' the collection, as we weren't expecting it!
As for the wedding, it was wonderful, the church, service, villa, photos, meal, music, fireworks were all amazing....
If I was doing it again myself, i'd definitively look at Tuscany...
