Playing multi tables is sometimes necessary as many poker rooms have similar start times. It is OK to begin with but but as the tournaments progress you have to focus more to be continually successfull. Luckily by the time a lot of players have been eliminated the pace of the games slow as those left are the most experienced, more accomplished and take more care over their betting. It is not for the faint-hearted but must be added to the card players portfolio, the more you practise the better you get. Use your available time, others may get frustrated by slow play but "on tilt" they give up their chips more easily. It is great excercise for the brain and keeps you on your toes, especially for an old man like me.
