At present, if you want the places to show-up in the normal post loops, as opposed to being in their own loop, you need to add a query_post before the loop as follows:
query_posts( array( 'post_type' => array('post', 'place') ) );
This will show posts and places…
If you want to run a loop with only places, you just need to add:
query_posts('post_type=place');
We will try to add this in naturally within the next version so that no modifications are needed to be made to the theme files.
Nonetheless, all “places” that you do make can be reached regardless of editing the theme file, which depends upon how you have your permalinks set. There is not much documentation available on custom post types and permalinks at this stage.
