My family; myself, wife and daughter will be spending 3 nights in Porto. This is our 1st time to Portugal and will be headed to Porto from Lisbon. We are staying @ The Sheraton. My daughter is well traveled so do not need to do Kid things as she enjoys the arts, museums and dinning. IF anyone has great suggestions for sites, eateries and can't miss things to do! We will be in Porto in late June. Any information that can be provided would be greatly apperciated and thanks in Advance.
