There is just so much to see and do in the WS... it can be over whelming
One of the things I enjoyed doing on our visits to WS is to begin by really exploring the pavilions that related to our family history.
Having never been to Norway though born into a Norwegian heritage, our 2005 dinner at Akershus was a real treat.
I got to taste some foods on the buffet I had not been exposed to before,
and discovered a new love of Norwegian cheese.
The next trip in 2009 we had done more family research and discovered my husband's family has deep roots in Norway,
and had to take a goofy picture of DH in the Stavkirke next to the red-headed wax figure of his great.g.g.g.g (add 30 more gs) grandfather, lol.
Nevermind he was never exposed to Norwegian culture until he met ME
Seriously, it's a fun way to learn more, just know it's a highly Americanized version of those lovely countries,
and Akershus has become a

infested

shadow of its former self- food wise
I think the food is better if you get an ADR for the opening of dinner than later on...
We are some of the few that actually
watch the movie at the end of Maelstrom...
and have a deep longing to go to Norge (but WDW trips keep cutting into that Norway travel fund

)
DH always buys me something special (of my choice) in the Norway shops-
I've gotten Christmas ornaments, cookbooks, and I am still drooling over the traditional Norwegian brooches and earrings
- I cannot decide and pick just one - maybe next trip
So we love the German pavilion and enjoy the Oktoberfest buffet there as well.
It's fun to look in the shops at all the merchandise from those countries, just be aware,
some stuff from every pavilion is imported- not from the country you would think- but made elsewhere.
I do not pay for "German" or "Norwegian" stuff made in china

(but you might not mind...)
So I would suggest starting with what interests you and branching out from there.
It took me something like 15 Epcot visit days over 4 different visits to finally go into France-
which just really does not interest me at all even still after exploring the pavilion...
There's just so much to see it really is impossible to see it all in one visit.

I hope you have a blast exploring!!!
