Hello,
I was back on Wed mid-nite. Thanks to all who have provided me info, advise and comments, arigato gozaimasu~

(especially evilerniex for the prompt reply)
We stayed at Hotel Wing International Hakata Shinkansenguchi, very near Hakata Station, with free breakfast (simple bread of 2-3 choices, coffee machine, orange juice, apple juice), a mini library, free onsen, a good choice of hotel.
As I travelled from Osaka-Kyushu-Osaka, bought the Sanyo San’in Northern Kyushu Pass, which saved more than 50% train costs. Good.
- It was indeed still very cold and sometimes windy (*brr brr), despite it is already April.
- Get to see sakura here and there a bit at Kyushu.
- Me did not get to enjoy as much as previous Japan holiday trips, partly becos too tired and a bit rushing, we walked a lot loh! But overall still ok, I get to go most of the places in my itinerary, not bad already.
- Japan shopping is still as nice as before, love their long shopping streets, small shops, kawaii stuffs, shopping mall basement of foods, etc… the more u c, the more u wan to buy! Heehee.
Fukuoka
Not many places of interests that are appealing, maybe becos after been to other prefectures, make me feel nothing special bah. I went to these places (more about shopping and walk walk):
Uminonakamichi Seaside Park (flower picnic festival), saw people having picnic and happened to see cosplay too.
Tochoji Temple.
Yanagibashi Market.
Tenjin Underground Shopping Mall (many shops!).
JR Hakata City (few shopping centres, Tokyo Hands, many shops, many restaurants, many snacks, etc).
Nagasaki
The
penguin aquarium is nice, but after been to the penguin parade at Hokkaido Asahiyama Zoo and mini penguin at Melbourne Phillips Island, me dun feel as excited. But still happy becos the penguins are really kawaii~!

The plus point is, we get to touch the little penguin, wow, unique experience!

Also get to see small and big sea animals. 3D virtual auditorium. Somemore, the entrance fee is cheap, so worth a visit. Went to the
Mt Inasa for the night view, before the trip I did hesitate whether to go anot, becos already expected will be very cold. But, I still went. It was super very cold and windy!!! (*brr brr) The night view is indeed nice with all the nights. Ate the popular Nagasaki castella cake (very sweet!) at the restaurant and enjoyed the night view.
Yufuin
Initially wanted to take yufuin-no-mori train, even reserved seats already loh, but failed to do so due to certain reasons, kind of disappointed, haiz. FYI, yufuin-no-mori train changed route, which take around 4hrs 45mins per trip, only 2 timings per day and limited to certain days only.
Yunotsubo Kaido Shopping Street is so nice, many snacks/desserts shops, many kawaii shops, many souvenirs shops, etc. I wish I could get to eat almost all the snacks and desserts, buy more stuffs, slowly walk around to go in every shop, but time limited, as the shops close around 5pm or so. My first Japan
private onsen experience was at here too. I love Yufuin~!
Hope it helps those who are planning Kyushu trip.
