We just got back from our 6-day WL stay, and we took our Mac Techno Classic (2004). It was a workhorse, we could not have survived without it. I loved having the full recline, Alison fell asleep in it several times and it left DH and I free to roam the park while she napped. One thing I would recommend is a large tote bag that folds and is pretty roomy. When you have to collapse the stroller, it will come in very handy for holding everything that was in the basket. Get one with big handles so you can throw it over your shoulder.
I also bought a SkipHop saddlebag which was great to store sunscreen, snacks, etc., and it stayed on when the stroller was folded, and was easily accesible. We also had the Maclaren Universal Organizer which was great. I wish I had brought an oversized sunshade (like the Protect-a-Bub), but the one on the stroller was sufficient enough.
It was our pack mule, and we loved it.
