Congratulations on your trip Kiwi Girl. I'm just back and can recommend mid November as a good time to visit. Lowish crowds and the weather was nice.
We have always stayed at the Holiday Inn in Walnut St which is about 15 min walk from the gates however I'd not recommend them (and wont stay there again) as the rooms are now very tired and the bathrooms more so. There are a stack of hotels closer that everyone has mentioned above. Use Google Earth to have a "walk around" the area to see what would suit your family.
We only spent one day at Disney this time (park hoppers are a must with them so close together) and found that Max Pass was well worth it for us to fully utilise the fast passes via the app and get ride photos. Mind you, it was just the two of us, but being able to book a RSR FP while still being in Disneyland finishing up a few rides there saved us a good 1 hour wait in the stand by line (FP for RSR ran out just after lunch). To give you an idea we booked the FP for RSR about 11 am and it gave us a FP return time of 3.30 pm. GoTG FP were also gone completely by 1.30 pm on a level 6 crowd day Monday.
Side note, security for DL is located outside Downtown Disney. The day we went we were through security in 3 minutes and having excellent bacon and egg rolls at the Earl of Sandwich by about 7.50 am (9.00 am open for DL, 10 am California Adventure that day) before joining the line up at the gates around 8.20 am. People who arrived at 9 am told us that they waited almost an hour to get through security due to the attacks that had happened in NYC the day before. Everything was being searched, so travel light and go early and you'll get more done.
If you buy your universal tickets online from them you get in to the Harry Potter area an hour before the park proper opens, which will save you time and crowds. We got in early at 9.00 am and had ridden FoTHG by 9.30 (if you get motion sickness wait for the tablets to kick in properly before riding it... ask Crazy Cat Boy how we know this! What a waste of a ticket! Doh.). They didn't open the bottom part of the park until 11.00 am which was disapointing to us as by 10.30 am we'd done the upper level and had to kill some time before they'd let us go down the escalators.
We stayed in Hollywood at the Holiday Inn express. I think given my time again I'd probably choose Lowes instead. It was closer to the metro station Hollywood and Highland which we used for 4 days and looked like a much nicer hotel. The Red line that runs through that station will take you to Universal inside 20 minutes (catch the free shuttle from the stop to the park, that's a very steep hill to walk up!) and to downtown in about the same. You can also jump off at different stops in between and catch the metro buses to La Brea and The Grove or train down to Santa Monica very easily. With only rudimentary knowledge of where we were going we managed to get around pretty easily. Google Maps when it was working for us was great with stops and arrival times for the buses.
If you decide to go downtown and want to use the Angels Flight Railway to go up and down the steep hill from the central markets it will only cost .50 cents per ticket if you have a metro pass and $1 if you don't. It's an adorable little trip and if you have lunch at the markets (lots of food options) and then go up to The Broad or the other galleries it'll save you some walking.
Santee Alley was interesting but it's a long and crowded strip so if your daughter gets tired easily I'd give that a miss. It's mainly cheap fashion so if you want cheap jeans it's the place to be.
We had dodgy wifi/data reception while we were downtown and found that the bike hire kiosks had pretty good maps that helped us out of some tight spots if you have the same problem!
If shopping is one of your I actually purchased some great tops and workout gear at
Walmart. Cheap and pretty good quality for the price. I have to say that this trip I found the outlet stores not to be as good value as they have been in the past.
HTH and have an amazing trip!
