When you check into the DLH, you will receive a sheet of paper titled: Magical Times at the
Disneyland Hotel. On the front it has information about the hotel, wake up calls, check out times, phone charges, that sort of thing. On the reverse is other information and that includes info on EE. This is what that specifically says (I saved mine from when we stayed there last month):
Disneyland Early Entry
As Guests of the Disneyland Hotel, you are invited to enjoy early entry into Disneyland on selected days. Early Entry allows you to visit selected attractions in Fantasyland and Tomorrowland 1 hour prior to Disneyland Park opening. To enjoy this offering, present your Disneyland park tickets and your Hotel I.D. card at the Main Entrance turnstiles. Currently, Early Entry is offered on: Mondays, Tuesdays, Thursdays and Saturdays. Please be advised that the availability of Early Entry and offered attractions is subject to change without notice.
That is the only place I have ever seen Disney print out EE info, is on these little sheets they give you at the hotels. At the Grand Californian, they give you a sheet every night (put it on your pillow when they do turndown). At the DLH you get one that doesn't list any specific date information at check in. Also note, that the Hotel I.D. card they mention is not your room key, but rather a small sheet of paper that you use for EE and charging to your room. It has your name, dates and the number of people in your room so they can make sure you are bringing in the number of people for EE that are on your room slip.
Your phone will have an automatic button to push that will give you a pre recorded message about park hours for the next several days. It doesn't say anything on that message about EE. I usually just called the front desk each night before an EE day to verify that it was still going.
I am with Hydroguy, why they don't put this information on their website is beyond me, it would make it so much easier!
