Sounds like a bargain these days. The time this sums brought me in the Aman are history.

Even if many have already said it: If you are only halfway interested and do everything in a hurry, 2 days is not exactly a lot (likewise in Rome it is only enough for a flying visit). As others said, Burano and Murano are pretty, but not on the same level as other sights: So if I had so little time, I would concentrate on the center (unless you have a total passion for glass).
