Allow several days for Portsmouth's naval heritage

How much of a one-week British trip should be reserved for Portsmouth's major naval-history sites?

Plan on about three days, or four for a more relaxed visit with time for nearby sites and return visits.

Roughly three days allows time for Portsmouth's main naval-history collections, with a fourth available to revisit a favorite site. HMS Warrior, HMS Victory, Mary Rose and the dockyard museums already make a substantial day's visit. The submarine museum across the harbor adds another collection, while Fort Nelson and Osborne House extend the itinerary beyond the dockyard. The recommendation assumes a visitor wants time to study the ships and exhibits. A faster itinerary is possible, but the panel disagrees about whether a tightly scheduled holiday leaves enough time to enjoy what is being seen.
