Disneyland in April, busy? Also walking from Disneyland hotel to Disneyland at night, Safe?

Yes - Disneyland is busy everyday of the week. Yes - It is safe to walk to the hotels & motels located close to Disneyland. Many directly across the street on Harbor Blvd. The streets are well lit at night. It is best to have reservations at a hotel since most if not all hotels are booked and your best prices are arranged in advance. There are tour pricing packages available although I dont know which are available. Also check the Disneyland website.
