Get the Triumph. For a 2.5 year old, the quest is really "too much stroller".
I have a Triumph AND a Quest. I have a 3 year old and an 18 month old. I bought the Quest when the baby was 9 months, I got it for the footrest (which he is very quickly outgrowing already) and the full recline.
I got the Triumph for my older son around when he was 2.5. He LOVES it, it actually reclines more than enough for a 2 year old to nap ,and a bonus is that the hood tilts farther forward than on the Quest for better sun protection, plus it is lighter and has a carry STRAP, rather than handle on the Quest. The carry handle makes it hard to carry the Quest AND manage a child, while with the Triumph, you can sling it over your shoulder and have both hands still free.
Honestly, too, the Quest does not recline ALL the way flat, it actually reclines about as much as the Triumph, so keep that in mind.
They both come with a raincover. All Maclarens tip easily, but it's easy enough to remedy that by using a backpack as a diaper bag and ONLY putting the bag on the handles when the child is IN the stroller. It behooves you to not store things in the basket anyway because if you need to fold up the stroller, you can't have stuff in there. Get used to carrying everything in a backpack so when you are at WDW you can just get your child out of the stroller, fold it up, and GO! We keep no more than maybe water bottles and a blanket in the Mac baskets, which are easy to put in the backpack when we need to.
I wonder what you didn't like about the folding mechanism on the Maclaren? I find it to be the best one there is. You can do it with one hand and the self locking mechanism is priceless! Plus, you can push it while it's folded or lock the wheels and it will stand up against a railing or wall. We use both our Mac strollers at
Disneyland and DH and I actually both prefer the Triumph over the Quest, for it's ease in carrying around.
I paid full price for my Quest at Babies R Us, but I got a GREAT price on my Triumph at Albeebaby.com. ($109) Try there! Free shipping, no tax, and good prices.
