if field free bool (tinyint), try this:

with test table:

create table `hotels` (   `hotelname` varchar(20) default null,   `dbdate` int(11) default null,   `available` tinyint(1) default null ) engine=myisam default charset=latin1;  /*data table `hotels` */  insert  `hotels`(`hotelname`,`dbdate`,`available`) values ('amsterdam hotel',20130503,1),('amsterdam hotel',20130504,1),('amsterdam hotel',20130505,1),('amsterdam hotel',20130506,1),('amsterdam hotel',20130507,1),('amsterdam hotel',20130508,1),('amsterdam hotel',20130509,1),('amsterdam hotel',201305010,1),('amsterdam hotel',201305011,1),('amsterdam hotel',201305012,1),('utrecht hotel',20130503,0),('utrecht hotel',20130504,0),('utrecht hotel',20130505,0),('utrecht hotel',20130506,0),('utrecht hotel',20130507,1),('utrecht hotel',20130508,1),('utrecht hotel',20130509,1),('utrecht hotel',201305010,1),('utrecht hotel',201305011,1),('utrecht hotel',201305012,0);
