The problem is with the echo line
echo "<table><tbody><tr><td>".$row_re['date_re']."</td><td>".$row_re['time_re']."</td><td>".$row_re['depart_re']."</td><td>".$row_re['arive_re']."</td><td>".$row_re['adult_re']." x ".$adult_re."=".$row_re['adult_re'] * $adult_re."</td><td>".$row_re['child_re']." x ".$child_re."=".$row_re['child_re'] * $child_re."</td><td><input type=submit value=Booking Now></td></tr></tbody></table>";
HTML will be generated like
<input type="submit" value="Booking" now="" />
so there shouldnt be any space. If you want to leave a space enclose the values in a single quotes like
<input type="submit" value="Booking now" />
