I think I can give you some advice, because just a few years ago I was in your shoes. I'm a Floridian who grew up on WDW, and in 2007 I decided to go to Disneyland as a "one time experience." Well... I loved it so much there, that I've been back 3 times since my first visit!
Disneyland has 3 official "on property" resort hotels, but all of them are quite pricey, especially the Grand Californian. If you are willing to pay $300+ per night (or $500 for the Grand Californian), it's a good experience to stay at one of their official hotels. They don't have moderate and value resorts like WDW has. There are several inexpensive hotels surrounding the resort, many of them in close walking distance. I can give a personal recommendation to the Portofino Inn and Suites on Harbor Dr and Katella. I stayed there once and it was very clean, well priced, and in close walking distance to Disneyland. I've also stayed at the Disneyland Hotel, and while it was a nice experience, I'm not sure if it's worth the jump in price. Staying on property in DL isn't as important as in WDW, since the property isn't nearly as vast. I've also heard good reviews for the Anabella Hotel and the nearby Best Western.
Like in Disney World, you can make dining reservations at Disneyland, and I'd suggest you do so. If you go during the busier times of year, the restaurants can get crowded. Here's the phone number to make dining reservations- 714-781-3463
Everyone's favorite fine dining experience at Disneyland is the Napa Rose, located at the Grand Californian Hotel. I'm also a big fan of the less fancy and less expensive Storyteller's Cafe, also at the Grand Californian.
My favorite restaurant inside the parks is Cafe Orleans, in the New Orleans Square area of Disneyland. If you go there, you have to order their french fries. Their fries are the 8th wonder of the world in my opinion. My favorite snack is a Dole Whip (they also have those at WDW). The Dole Whip stand at Disneyland is right in front of the Enchanted Tiki Room. I've also been a frequent customer at the Main Street Bakery, a great place to grab a cookie.
If you want to grab a meal outside the parks, there's plenty of selection around Harbor Blvd. A couple visits ago I remember eating at a PF Changs and a Cheesecake Factory nearby.
I don't know anything about renting scooters, but I hope I helped! You will love Disneyland. It doesn't have as much to offer as the entire Disney World resort, but Disneyland Park is the single greatest Disney Park on the planet. Once you've been to Disneyland, Magic Kingdom at WDW won't ever feel quite the same. Have a great trip. I'm going back in February of 2011.
