[Closed] Wordpress.com and Google Maps

So...I've been trying to embed a map I've made in Google (both Classic and the fancy new Maps Engine) into a Wordpress.com blog (note: not a blog created with Wordpress.org and hosted separately).

And it seems it's not happy with either using the <iframe> tags. Wordpress creates it's own short URL from the <iframe> info, but doesn't seem to like maps with more than one location, or anything from the new Engine. Anyone else come across this and found a workaround [that doesn't involve using Wordpress.org and its plugins]?

Map is here for interest: https://www.google.co.uk/maps/ms?msid=208723974359109451702.0004e8e33d72257992377&msa=0
