An interesting observation concerning II

I just searched for Hawaii with request first ( I think that's what it's called ) using a 1 BR Worldmark and both these Marriotts showed up:


Marriott's Maui Ocean Club
Lahaina , HI , USA
Nov 22 2015 - Nov 29 2015
1 BR


Marriott's Maui Lahaina & Napili Villas
Lahaina , HI , USA
Nov 29 2015 - Dec 06 2015
1 BR

Doing the same search using a studio, only the Marriott's Maui Lahaina & Napili Villas showed up, and the check in is a week out.

The same day check in for Marriott's Maui Ocean Club did not show up using the studio.

I thought maybe the Maui Lahaina & Napili Villas got taken, so I refreshed and did the search again using a 1 BR and it was still there. Why would a check in a week out show up and a same day not at all ?
