. Unlike Universal, there are no blackout days.

There are many, many blackout dates.
Like others have said, it's dependent on what her classification level will be. Regular employee Maingate passes are up to 3 people (or more if you have more dependents), 16 days per year. These are good at WDW, DL AND DLP, and HKDL if you want to go international. She can sign herself in at anytime (except sometimes even CM's are blocked like for Mark Hamill at DHS or the 24 hour party). She has to be present to sign you in, but as you are a parent (and other eligible relationships) she does not have to stay with you. She has to be the one to make any FP+ reservations through her
MDE account.
Additional Regular employee benefits include
Twice a year, two "comp" tickets. These are single person park hoppers, but NO blackout dates. (Temp Casual do get these)
40% Friends & Family rate for hotels.
20% off full service food locations up to the number of people allowed on your Maingate (it used to be the whole table, but they changed the wording recently)
Merchandise discounts are not transferable CM, spouse, dependents only. Yes, people "share," but it is grounds for termination if you get caught.
Holiday discount booklet offers additional discounts like one time use discounts for food and merchandise at a deeper discount than normal. And single use discounts for the number of people allowed on your Maingate at Disney Quest, Water Park, mini golf, free popcorn/soda coupons, free photo.
Additional discounts can be for things like the parties (although after all the sellouts this year I can see them cracking down on that), limited to the number of people on your Maingate.
Discount, last minute rates for
DCL up to 3 cabins, CM must travel. Also, discounts for Adventures by Disney, but CM must be in the same room.
