I have stayed at all three hotels in the past, and December 2004 we stayed at Grand Californian and there is no looking back for us! You absolutely cannot beat the location!!! We had DTD views, so I can't comment on Theme park, although I am dying to try it!
Now let me say that DLH may be easier for you since you have no stroller to contend with. FOr us, having to fold up the double stroller, carry all the stuff inside it, and handle a toddler and baby is too much, so we don't get to make use of the monorail. At the end of the day, it is a long walk for us back to the DLH. Plus we love Whitewater Snacks in the Grand, as well as the Storytellers breakfast, while we aren't fond of the restaurants at the DLH as much.
As far as the pools, everyone with little kids always chooses the DLH as the best pool, but we don't feel that way. Yes it has a small pirate ship sitting by the slide, but other than that, there's really nothing special about it to warrant staying there just for the pool. Also everyone likes the Tinkerbell wallpaper, well we get back to the room so late, that the kids are already asleep or falling asleep, so we have never had the main lights on long enough to charge it!! Stayed there 4 times already and have yet to see the Pixie Dust glow on the darn wall border,
The kids love to hang out in the rocking chairs downstairs, and I know that anyone can enjoy the lobby regardless of where you stay, but I do enough walking when I am there, it's nice to just already be there!
I know this doesn't pertain to you, but we were there at Christmas and the decorations at the Grand put the DLH decoration to shame. We went over to check them out and there was a tiny little tree in the lobby and not much else that we saw, maybe a few wreaths! Not a big deal, but it still was nice to come back to the Grand every night!
Well I hope I haven't made you more confused. I know the price difference for us hooked us into the DLH a few times before, and every time during our long walk back (even though it's through the great atmosphere of DTD, it's still long at the end of the 3rd, 4th day, etc..) I would look up and really wish we had spent a little more to stay at the Grand. I hope you have a great time, let me know what you decide!!!
