I'd say it's rather too complicated, and all being in one long paragraph doesn't help. You can definitely delete the bit about 'room available as soon as possible' as that would mean getting whatever is free from the Ready Room inventory when you get there, rather than being pre-assigned a room.
I also wonder if referring so specifically to "primary" and "secondary" requests sounds rather too formal, as if you've just read a FAQ on the internet...

You are also asking for conflicting things (e.g. river views close to the food court in AB, when you have a King Bed booked, are not easy to find - see my floorplan maps).
I would suggest something more along the lines of "We would love an Alligator Bayou room fairly close to the food court if you are able to arrange that, and also if possible to have a nice view, such as a corner room overlooking the river or a pool." You could give a few room numbers too, but only use them as examples of the sorts of room you would like (if you make them all ground floor, perhaps someone might even take a look to see if any of those happen to be free?).
