So what are you suggesting I do here?

I see the following with $TERM in my .bashrc:

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color) color_prompt=yes;;
esac
...
# If this is an xterm set the title to address@hidden:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)address@hidden: \w\a\]$PS1"
    ;;
*)
    ;;
esac


and on another remote host:

# If you're on an xterm, change the "address@hidden" and directory in
# titlebar
if test "$TERM" == "xterm" ; then
        PS1="\[\033]0;address@hidden:\w\007\]\@ \! address@hidden \w \n\$ "
else
        # prompt will show: time command address@hidden directory newline and $
        PS1="\@ \! address@hidden \w \n\$ "
fi
...

Have a safe and fun trip.  Hope this gets to you before you leave.
