How long should I plan on spending there? 2 hours, 5 hours?

At the market.....2 hrs.

Depends what all you want to see and do. 1 hour is enough to get a general idea of the place. But if you want to have a meal or do some shopping maybe 2-3? Not sure what you'd do with 5 hours. It's not that big. Do be sure to go "down under", there's several levels of shops below in the main building, besides what's obvious on the street.

Hmmmmmm, wouldn't 'the market' be named after "Pike PLACE" and not "Pike STREET" ??

The "Pike" in Pike Street, Pike Place (a north-south extension of east-west Pike Street) and the Pike Market, was John Pike, a Seattle pioneer who bought much of what is now the Seattle harbor area from the federal government, shortly after the government obtained it through a "treaty" with the local native Americans.

No relation to Zebulon Pike (as in Peak.)

I just referred to it as "there". I didn't want a third English lesson. I guess it was a big big deal to put an s on the end of it for some.

an s a s.

Sorry, I didn't mean to make a big big deal. Lots of people new to Seattle spell it various ways.

It's just that the name of the Market is spelled like the location, Pike Place at the end of Pike Street, not like belonging to the Pike's family.
