Okay dude... you are VASTLY underrolled for the $1000 and $2000 games. I have no idea if your skill level is sufficient but seriously, stop playing at these stakes or you will lose all your holiday money. I am deadly serious - it's not worth the ENORMOUS risks you're taking.

If you want to play cash inbetween MTTs, then you're rolled for $400NL (though again, do you have the skills? No reason to assume not, though if you're playing a laggy, high variance game even 31 buyins may not be enough and perhaps you should consider $200).

I really don't mean to be patronising - I can't even win at $100 so I'm not one to talk - but playing those stakes with that roll is a recipe for swift and inevitable disaster.
