--Julia (for her medical knowledge, and keen mind, and just being HER...
which, BTW, makes me wonder how Julia would deal with surviving on a deserted island with all that tweed... cut 'em down and make tweed mini-skirts and tank tops? LOL Hmmm...then I'd probably want Barnabas along so I could see his reaction to that...and to help Julia with any meticulous work that needed to be done. Maybe his cane would come in handy...)
--The hand of Count Petofi - could help in several areas...if you're lucky! LOL
--Magda - she'd tell our fortunes, help with the meals, help with any other work needed to be done...and I'd have someone else to bitch with, cry with, and someone to give me a swift kick in the arse when need be.
--Sandor - similar reasons. With him and Magda we'd find our way out of that island in no time, honey.
