We are flying to Orlando this week really JUST to see Harry Potter world this week. Now i'm not sure if i should buy a 2 day package (vs. the 1 day ticket for IOA) and do Universal Studios the 2nd day (we're there 2 1/2 days total) or should we just hang at the Royal Pacific resort (pool, etc) on the 2nd day and chill. My kids (ages 10, 9, 6) are HP fanatics but not big roller coaster or rides kids so not sure we NEED to do the 2nd day at Universal Studios, but don't want to be bored on Saturday esp. if it's a bit cool for swimming (72 degress is the predicition)? If I order online it's an additional $150 to buy tix to Univ Studios on top of my IOA tix. If i wait till we get there and decide we should do US on Saturday, it will cost me another $430!! help!!
