Google maps

[SilverBoy]

Hi

At first point I have to tell that, I have no experience with google maps, so maybe my questions are very stupid ^_^.

I want to lunch hotel reviews section in my site, and I want to add hotels which are exist in my reviews as points in custom google map, so the first question, how I can get unique map for me, and then how I can add locations to it and give them a hotel symbol, the last question is, how I can linked the location in the map with URLs to open the connected hotel with it's location in the map?

I want some thing like the map in this link.
