We are flying into Detroit Metro and our flight gets in at midnight. We are going to just get a hotel at the airport that night, and my dad will come get us in the morning. I will have my mom with me who doesn't move around all that well. I am wondering if it is worth the extra cost to stay at the Westin at the airport, where the shuttle goes every 10 minutes, or save a bit and get an off site hotel. We will have a shuttle either way, but I wasn't sure how long we would have to wait given the fact that it will be about 1 am by the time we get on the shuttle. Thoughts?!
