Transport - Travelling from Kansai Airport (KIX) to Nagoya JR station.

Hi
My family (2 adults and 1 child) will need to make our way to Nagoya JR station (to check into Marriott Hotel) in Dec 2014. I will not be buying a JR pass.

I know there are a couple of ways to get to Nagoya from KIX. Using the Kintetsu pass or travelling to Shin-Osaka and then take a shinkansen to Nagoya... Are there other ways besides these 2?

• I am deciding between the convenience of travelling and the cost of travelling (I am thinking to get Taqbin to send my luggages to Nagoya so that i can travel light when i make my way to Nagoya)
• If I travel using the Kintetsu pass wide ... I need to change train at Namba (Osaka) right?

Thanks & Rgds
