Most parkhopper tickets, for 3 days or longer have a day of EE built into them. The only 3+ day ones that I've heard sometimes dont include it are discounted tickets such as those sold on military bases, and and that is not an "always". So, if you have longer then 3 days on your tickets you should have EE regardless of where you are sleeping.
If you stay at one of the 3 disney hotels you can have EE each day it is offered during your stay. That is not hard fast, written rule, its a special they have been offering for about a year now.
EE is currently offered on Mon, Tues, Thur and Saturday. It is one hour before the park opens, and its Fantasyland and part of a couple rides in tomorrowland.
