Emirates Airlines Skywards - DXB Airport hotel

clicking on the Dubai Airport hotel link on the airport website takes me to the http://www.dih-dca.com/dih-dca/reservation/reservation_Date_Request.aspx link.

The wording/photos on the website leads me to believe that this is the reservation site for T3 Hotel also. The rooms are ridiculously high priced and secondly there are no rooms available for 3 weeks in advance. Is the site reflecting the right information and availability or is there any other way of contacting them.

ok, i contacted them via email at dih@dih-dca.com, the replies were prompt same day, but the pricing is still high about $220 for 6 hrs.

What's the difference between the two hotels? There's apparently one in T1 with 88 rooms and one in T3 with 253 rooms. Also, can one get from T1 to T3 without passing through security/customs/immigration?

Thanks.

Yes

booked into the T1 hotel last week and showed up at the T3 hotel and they moved the reservation for me with no issues.
