So I am back from my trip and thanks to all bro for info.
I have some updates (non sexy stuff)
Nagoya Citywalk fun world
no longer has unlimited rides option so it can be quite expensive depending on how many kids you have and how many rides you allow them to go on. There is really very little people during weekdays which is actually a disadvantage to you because your kids will finish the rides very fast. There is no queue.
1 or 2 hours there and it is already costing u as much as going to a theme park in Singapore.
The only option now u can do is to top u the card and pay for each ride using the card. You can use the card for all the adults and kids in your family.
Nagoya Hills Hotel
It is very near the shopping center. U just walk across the road from the back of the hotel. It is good for old people who cannot walk too far. The hotel is quite good. They have Smart TV too. Only thing is you have to ask for rooms facing the shopping mall as the rooms facing the road is really noisy. Motor bikes at 2-3 am screaming at you. Light sleepers will have trouble sleeping.
Wey Wey seafood
There is now another seafood rest right beside it and the staff will fight for your business so u can ask for a discount like I did
Kids Indoor playground.
There is a indoor playground - happy kids in the shopping center itself 2nd level so another option to bring your kids. Unlimited play time so its great.
Sexy staff in next post.
