It looks like we're competitors. That said, in the spirit of tuggers helping tuggers I'll give you some tips. When you read call at 9:00 on the first day the inventory opens it means 9:00 not 9:01. I actually dial at 8:59:57. It requires some practice to see how much time it takes for the phone to ring on MVC's end as close to 9:00 but not 1 second before. I've been doing this now for about 3 weeks and I just snagged Christmas week at MFC a few days ago. I've never seen that open up in the 10 years or so I've looking.
As for RC there are three days open in JAN but nothing for 7 days at Aruba or the STT resorts. Good advice to look 11-13 months out but make sure to use the same 9:00 trick at the 12 month mark also. I n the past when traveling for myself I have picked up individual days and managed to fill in a week with three or more reservations. That's unwieldy if you plan on renting the unit as MVC won't combine reservations until two weeks out.
Keep checking as often as you can online, I recommend daily. As to checking online at midnight the day of the reservation I've snagged a few like that over the years usually around 3-4 AM. I'm fully retired now so I don't work nights anymore so I haven't tried that in awhile.
Good luck
