Welcome to the board.Unless you want to do gravel roads there are really only two circuits of the peninsula. The shorter SH25 and SH25A and the longer circuit using SH25 plus SH2 between Waihi and Paeroa, and SH26 between Paeroa and Kopu. The longer circuit is well worth taking, especially for the stretch from Hikuai to Waihi, via Whangamata. SH25A is also worth riding, in both directions.If you want gravel roads then the Tapu-Coroglen and 309 roads are good for crossing over the peninsula. There are also good gravel roads heading north from Coromandel township.Can't help you with the accomodation options. Sorry.
