We own 3 different Maclaren strollers, the Volo, the Quest and the Techno, and hands down, my favorite is the Quest (the one we have had the longest).
We bought the Quest when our oldest was 3.5 years old and it has endured several airplane trips and many vacations, some to well paved places to NY or WDW, but also to pebble roads, all this with an older child.
The underneath storage can fit a lot more than you would think, what I would do if I wasn´t going to be folding and unfolding, is put the stuff in different zip lock bags (ie, one for the extra clothes, one for snacks, one for sunblocks) and just take out the one we needed. They also sell saddlebags for the stroller and those work great too and the stroller can be folded with them on.
What I love most of the Quest above the other two, is that it has a very good recline (not flat like the Techo, but it is much lighter) and, for older children, it has the deepest seat, which makes for a more comfortable trip, it can be steered one handed even with a heavy child in it (we used to have a Combi that was a pain to push with a 1.5 yo) and it has a canopy and rain shield too.
