I haven't read this whole thread but I'd just like to recommend 2 places. Sea World Nara Resort is the most kid friendly place that I have ever stayed at yet had fun myself...eg a nice meal with my DH while the kids were at a Kid's Club. Secondly, we have just returned from The Heritage Sebel in Victoria's Yarra Valley. This surprised me... at first it didn't look child friendly at all.... but they were very accomodating and my children were more than welcome to use the facilities such as the indoor pool (floaties/pool toys included). The reason I mention the Sebel is because their Retreat has a full on Day Spa with every pampering treatment you could imagine. Admittedly my DH and I tended to "take turns" looking after the kids in the room and venturing out... but our room, a suite was huge, more like an apartment.... and had two TVs and 2 toilets which is always a good thing with a family! Also, nearby you have Healesville Sanctuary which is wonderful to do as a family.... and the Yarra Valley Dairy which is a foodies paradise and interesting for the kids as the calves are very friendly and you can get a nice close up experience... we plan to return to the Yarra Valley within 6 months to do it all again... such an easy short revitalising holiday if you live in Melbourne.
