You can of course use `C-x C-v' to change directories without multiplying
buffers.

Being able to not multiply Dired buffers seems to be a pretty common
request (not necessarily on emacs-devel, but in general).

For that, Dired+ offers command `diredp-toggle-find-file-reuse-dir'. 
It toggles whether Dired `find-file' commands, such as `dired-find-file',
reuse directories.  A negative prefix arg means do not reuse buffers; a
non-negative prefix arg means reuse.

For reusing, this essentially substitutes `find-alternate-file' for
`find-file' whenever the argument is a directory.
