disney sea is a place to empty one wallet lol...i love it so much i even hv annual pass last time

You are not going on the 1st week of May right? It's Golden Week, so sure will pack like hell.

I was able to do most of the popular rides on a weekday, without purchasing Express passes. 2 key tips are -

1. Arrive early like 1hr before opening time so that you are in the front part of the queue. Right after you enter the park, just run or walk fast to the Harry Potter area first and queue up for the ride. Shouldn't take you more than 30-45min queue even if you are not running fast like everyone else.

2. There is a parade around noon (can't remember the exact timing). Watch it near the start of the parade (i watch it somewhere around the 4D Theater). When it finish at your side, the parade will still go around USJ for about another 45min. Use this period of time and go for the popular rides. For e.g., it only took me less than 5min to ride the Amazing Spiderman 4D attraction.

Maybe to really maximise your chances, you can buy the Express Passes to shorten queue times for some of the rides. If so, i think you can really try almost all the rides, though not all are that interesting

EDIT
Assuming your wife is not so extreme and don't ride roller-coasters, there are also single-rider lanes which only take you 10-15min to queue.

u going during golden week? goodluk...the amount of tourist and locals can drown u during golden week...USJ is all about fun roller coaster tho unlike disney

once u enter early in the morning, straight run to harry potter park first, its one of the most popular 1. rmb to try the butter beer at harry potter park there *its non alcohol dun worry*
