Answer 1

http://de2.php.net/manual/en/function.mysql-fetch-row.php
mysql_fetch_row() takes not the query itself but rather the result from the mysql_query command (which is a resource).
Look at the example at the PHP Documentation (linked at the top) and you will get the functionality of mysql_fetch_row.
Maybe the assignment of $query_hotel_search can clarify the situation.

Answer 2

You are using a codeigniter object as mysql resource. Instead you should use object iterator provided by codeigniter to loop through the results.
foreach($query_hotel_search->result() as $row)
{
// $row as object
}
foreach($query_hotel_search->result_array() as $row)
{
// $row as array
}
For the second part (UPDATE), mysql_fetch_row() return an enumerated array. so you should use:
$units = unserialize($row[12]);
