I update my laptop at work and rsync to other machines when I get home.
Here's a variation on that:

... On fasthost, modify /etc/yum.conf to set keepcache=1.
... If you've not set keepcache before, then you may still end up downloading
... dependencies (to slowhost) not kept on fasthost from previous runs.

fasthost# yum install/update [ --downloadonly ] THE-PACKAGES-I-WANT
fasthost# rsync -avP --include='*/' --include='*rpm' --exclude='*' /var/cache/yum/ /media/STICK/yum/

... go home ...

slowhost# (edit /etc/yum.conf to set keepcache=1)
slowhost# rsync -avP /media/STICK/yum/ /var/cache/yum/
slowhost# yum update/install

This will only copy the RPMs; yum will still download metadata (see yum.conf for "metadata_expire").

... optionally, rsync RPMs back to STICK, then back to fasthost
