Also my kids are 9 and 6. Worried about June crowds but have heard it is always busy nowadays- is june during the week going to be horrible? TIA!
Imagine Magic Key is blocked all of June.
Enchant Key is blocked every weekend in June, and the whole rest of the month after June 10th.
Believe and Dream Keys are wide open for June.
Of course, "busy" is subjective. Many years we go the first week that the lower passes (now called Magic Keys) are blocked out. It seemed less busy at that point since so many passes weren't able to attend without a regular day ticket.
We never stay on-site at DL, so I can't really comment on the benefits. Staying off-site can save so much money.
You said the Marriott Courtyard was $100 less a night. Each night you stay, that difference is:
2 adult sweatshirts -or-
3 adult t-shirts -or-
15 Dole Whip floats -or-
16 churros -or-
Dinner for 2 at Blue Bayou -or-
Lunch for 4 at Cafe Orleans -or-
16 Dole Whips -or-
3-4 pairs of Minnie ears -or-
4-5 pairs of Mickey ears....
Several off-site hotels and motels are closer to the main gates of
Disneyland, unless you are staying at Grand Californian.
