you won't go to maps.google.com for hotels but:
a/ what if there is a search box like with flights? try search for [berlin paris] on google.com
b/ what if pages like this: [maps.google.com...] start to show up.
c/ both above will be promoted in SERPs :)
The longer I watch Google, the more convinced I am that only way to make decent money ON the internet is going to offer OFFLINE services, i.e. service that will be hard to replace using algos.
