In your model d is declared as 

> param d{i in I, k in K};
> /* duration of room type i on day k */

and in the data section you specify:

> set I:= Mainshort Mainlong EOPSshort EOPSlong; # room type
>  
> set K:= Mon Tue Wed Thu Fri; # days of the week
>  
> param d: Mainshort Mainlong EOPSshort EOPSlong :=

> Wed 7.5 9 7.5 8
> Thu 7.5 9 7.5 8
> Fri 7.5 9 7.5 8;

Thus, element d[Mainshort,Mon] exists while d[Mon,Mainshort], which
you refer in constraint1, doesn't.

Check indices!
