Hotels within 30 mins of Glen Cove?

Anyone know of cheap hotels on the North Shore near Glen Cove, or anywhere within a half hour from there? I saw the hotel price listing thread, but I don't know long island very well, so I don't know what's close to Glen Cove and what isn't.

I'd like to offer some of my guests a lower end price option. Most are staying with us at Harrison House, but I don't want that to be the only option. I'd love a place where the rooms are around $100.

Also, the East Norwich Inn in East Norwich/Oyster Bay is very close to Glen Cove as well - I think we blocked rooms for $119/night which was less than the Holiday Inn quoted me.
