Zadar Accomodations?

My girlfriend and I will be travelling to Croatia for a week in Late June. We are arriving in Zadar, by plane, at 9:30pm. Because of our late arrival, we're looking for a place to stay for at least one night in Zadar. Any ideas? Thanks

PS... We have to be in Split two days later. We looked into the buses south, but the ticket office closes at 10pm and we don't want to risk not getting a ticket and having no place to stay. Also, we have to use public transport because we won't have a car. Finally, we've used tripadvisor, but have not been impressed with the limited selection.
