The Mount and Tauranga have lots of amazing places to stay and lots of fun things to do while you are in the Bay of Plenty. If you're organised you could book a bach with a group of people or if you feel like splashing out there are some beautiful high rise apartments at the Mount with great water views.
Only 300m from the wedding venue is Bethlehem Motor Inn. It has all the comforts you will need, and some little luxuries like a pool and spa, a tennis court and a golf net.
