The first couple of years I was a first timer with a group of friends who were regular visitors and we did one day visits.
The very first time I went I was just so over whelmed and had no clue about anything. I was then and still the same now not into the big coaster rides. I basically just knew about Fantasyland , Pirates of The Caribbean and Star Tours.
One that first time in
Disneyland we basically didnt have a plan, other than lunch at The Plaza. My friends were great but I must have been such a pain. We started in Fantasyland and then my friends said what do you want to do next. I dont know, um Pirates, ok lets go to Pirates. After Pirates lets go to Star Tours, then my friend suggest Haunted Mansion, me clueless, um whats Haunted Mansion. Its a haunted house, funny scary, not scary scary, my 5 year old son loves it, me ok, if a 5 year old loves it, it must be ok, so we go back across the park and over to Haunted Mansion etc ect you get the picture.
I loved that my friends let me for the most part suggest rides, however as we just had one day they tried to give me the best day ever at Disneyland and we were go go go. I would have loved to be a bit slower, to take in all the sights and sounds. Also we ate at The Plaza as that was whee they had lunch every time they went to Disneyland. Since I have been my solo trips I haven't eaten at The Plaza.
Also my friends are from California and are used to the heat and sun, Im from Ireland and I'm not. Now on my solo trips I try to be inside either shopping, a restaurant or a show between 1pm and 4pm , where as on that first day, my friends didnt realise that my body didnt like the heat and I needed some down time in the afternoon.
My friends tradition every time they go to Disneyland is to get pizza to go in the evening and find a spot for the fireworks in front of The Castle and eat their pizza while waiting for fireworks. Now on my solo trips I do a Fantasmic Blue Bayou dining package and I dont watch the Fireworks from The Castle.
After all that, my advice is to talk to your friend. Ask about expectations for the day, what rides and attraction she knows about. Ask about food budget and the type of food she eats. you said about walking distances, so maybe plan to sit and people watch every so often. You and your daughter might do Indiana Jones, then Pirates, then down to Splash and then Haunted Mansion and then walk over to Tommorrowland but your friend might only be able to Indiana Jones and then Pirates and then maybe you might have some Mickey Benits and a Mint Julip, and then into Haunted Mansion, then take the train from New Orleans Square to Tomorrowland.
