Mariana Resort and Spa is our hotel of choice for our several trips to Saipan each year. It is in very good condition and boasts very nice ocean views from clean, spacious rooms. The staff provide excellent service and the grounds are very pleasant for an after dinner stroll. The spa is, by consensus of ourselves and several locals, the best in Saipan and is certainly worth the extra ten or twenty dollars a day for the scenery alone. While it is a bit off the beaten path, that's not such a big problem on a small island like Saipan and convenient, free transportation options abound for the fifteen minute trip into town for additional dining, shopping, etc.
Be sure to reserve a couple months in advance and look into the discounts for advanced booking, five day stay, and the slight additional charges for the delicious breakfast buffet and spa package. They have an executive course as well as an 18 hole golfcourse which they sell some packages for too.
Mariana Resort offers much more than most of the hotels on Saipan for a bit below the same price.

Food servers should always tie up there hair. I went to Puduo King Cafe and there was one waitress with a long hair which was flying into the food that I ordered. That was so gross....Pls. not cleanliness is next to Godliness...
