my friend (who I should say by now is a stroller fiend) who has 4 Ruthie's age and younger had one... and I've tried out all her strollers except a few...
she had one and she loved it... it was made better and also was shorter than the typical graco that it resembles... she's petite, so shorter was something she was looking for.
The adjustable handle made it tall enough that I could push it, but I kicked the back wheels if I wasn't careful with my big size 11 shoes.
It isn't nearly as compact as the other combis... what I'd do for disney is get any combi... going by which you like best... and then get a carry-you piccolo or siena to convert the bar to a tray, OR... because the price is SOO low due to it just not selling well, get the Graco Cleo for 90 bucks! It has the features you like on the pliko light (though it's really more like the p3), plus a tray.

with either one, though, I'd consider also getting an add-on sunshade from protect-a-bub
