Can you check in with a debit card or cash if you don't have a credit card? Is there a down deposit?

No. Must be a credit card. They will hold 50 dollars off said credit card and return it once you check out.

As far as I know a debit card is fine but they put a hold on the card. On a debit card a hold actually takes the money out of the account. Call the hotel directly and verify how much they hold.
