From there it only takes about one hour to get to the entrance of Yosemite and about two hours to get to the trails. Probably longer due to taking pictures along the road.
Hotels inside the park are expensive. But you can get a heated tent at a reasonable price at Camp Curry. But be prepared: It can be quite cold in November! But you wake up to an amazing view.
Just right outside the park, at El Portal, there are a few Hotels where one can get a deal through Expedia. We stayed at the Cedar Lodge. But: No free Wifi, , no coffee, etc. But the rooms are ok. However, the food at this place is supposed to be pretty bad if you believe TripAdvisor ratings. It was supposed to be better at next to the hotel Yosemite View Lodge: The River Restaurant & Lounge. So this is where we went. The salad bar was great. Lynns Burger was burned (really totally black) at their first try, but she sent it back and got a good one quickly.
Getting food (some cheese, bread, juice and milk) for the hike at a local grocery store is probably the best option.
Some of the hiking trails are paved with asphalt to be accessible for everybody. Some are a bit more difficult and go into the wilderness. The best way to select one that suits your skills is the Chimani Yosemite App. It is available for Android and iOS. They also have an app that features all National Parks in the USA. I really recommend getting it! The links point to the Android version in the Google Play Store since I do not have any iOS devices.
Wildlife in Yosemite Valley is not so wild anymore.
