There are computers with internet access in the convention area of the DLH I'm sure the other hotels on property have one as also but I've never used them. I also think there is a internet site that charges at the Ramada across the street but I dont know what they charge.
Some of the good neighbor hotels have a computer with internet in the lobby. I cant remeber them now but I'm sure they have them listed on their websites.
Hope this helps a little. Sorry couldnt be more specific about good neighbor hotels....drawing a blank!
