It deoends on the ages of people going, the interests in the people going and most important WHEN you are planning on going..Without more info it is hard to answer
well we are going at the end of February there will be at least five of us one infant a four year old an 11 year old me and my husband and possibly grandparentsthe 11-year-old love scary rides fast rides whatever rides the four-year-old not so much obviously the infant can't go on that stuff so me and Dad will probably be doing rider swap if they even have that there
They do have child swap at most of the popular "thrill" type rides. If you can afford it, I would really suggest you get the Express Pass. It makes a world of difference when you are able to walk right on the majority of the rides, giving you plenty of time for the ones without express that tend to be most people's priority (I.e. the HP rides.)
Then why don't you each pick one ride from each park that you absolutely MUST do, and find a nice order to do them in. While you are doing that you'll surely end up passing by a ride here or there and someone will say, "Can we please go on this, there's like no wait!" The beauty of Universal is that you really can sort of just wander around and ride whatever. After you've finished all the rides you had planned you can go back to everyone's favorites or do something new.
P.S. If you want to ride the train between the parks, the best way is from King's Cross Station to Hogmeade.
So I don't need to super plan like Disney?! That would be great, the only problem I for see is my daughter only picking one or two rides she wants to go on every roller coaster
End of Feb is moderately busy, mostly because of the events in daytona (Races, bikes, etc.) Presidents day weekend being the busiest. With one day you won't get to do everything, but you may be able to get some highlights.
