Multitabling....necessary?

FWIW, I don't play many hands (maybe 15-20K since March of full and SH tables) so I don't multi-table more than 2 tables at a time. I like a table of SH and a full ring running, one is slower more methodical while I can focus on the SH table more.
Sometimes I only have an hour or so to play, and I don't want to drop 75BB with too many tables open and not be able to put the time in to get it back.
