We found, particularly when they were little like your punkin, that we did need toys. They get pretty inventive at that age, and if we didn't give them stuff to occupy themselves while we were getting ready or relaxing or having a snack or something, then they would find it themselves. Cords were a big favorite!
At that age we brought the big fat crayons and a paper tablet (which, by the way, we brought into the parks with us and when we were waiting for parades or our meal, we pulled out.) Bubbles is another one. (This, by the way, is a favorite when waiting in line for busses!) I invested in a bunch of those plastic chain things and we had a whole variety of things on the strollers to play with, little mirrors and noise makers, etc. Kept them busy during "down" time also, and at 13 months (which is when we went), gave our drooler something to gnaw on all the time since she was teething.
One thing we always bring is bath toys. It's familiar and gets them in and out of the bath, and at some of the pools, we can bring them down there to play with.
Other items that have worked well for us, cars/trucks (doesn't matter gender), magna doodle, dolly/baby, legos/duplos, blocks. Don't need alot, just some that will keep them occupied for brief stretches.
