I am trying to decide whether or not to go for the 4 day pass to Universal Orlando. It will cost for my family of 3 about $175 more for the 4 day pass ($357 for single day) , plus all the other costs you can't avoid, like parking, food, souvenirs and who knows what.
I'd rather stick with the 1 day but the wife just keeps talking about how much you save and I keep telling her that when you add it all up it's still a lot more.
So, the question is does the park has enough going on to warrant more than 1 day?
Who and what ages are all 3 of you will make a difference.
also, when you say 'buy 2, get 2', is that - 'you buy for 2 days, and get another 2 days free'? if so, they got you where you can't wriggle : because to see both parks of Universal, you need 2 days, but 4 days is overkill.
And that if you have a kid of 10 years or more and wants to do all the rides in Islands. For smaller kids you could spend a minimal time (2 hours max, maybe even less) at Islands and still be very happy.
If you are not the kind to go for the speed rides (or at least not all of them), then you might be able to manage in one day, but beware that it would be one looong, tiring, day.
You could check one thing - if they'd allow you to use the other 2 days at some other time. Long ago, I got some deal like that that allowed us to come back for the 2 remaining days, as long as it was within the next 365 days. That could make it worth it. Otherwise, your decision is just between - do you want to do less, but finish off in one day, or do you want to do all, and spend two days to do it. The other two days might become a bit boring for you.
Whatever you do, try to get there when the park opens, and get a local hotel for the night, and don't do like I was forced to do at times - drive back on a 4 hour-trip at the end of a tiring day at the park. Came close to driving off the road at times.
