This is a different overflow hotel and I believe is closer than any of the other overflow hotels. Assuming the weather is good or at least tolerable [yeah, I know] it looks like it is a .8 mile walk or about 20 minutes along the Charles. In addition the rate at the overflow hotel is $99 per night which is a savings of about $25-$30 per night when you include taxes. So, you might want to check it out.
