My 1 week at Hokkaido JaLS

I signed up for only a week because I was unsure what to expect. It was my first time in Hokkaido, and the first time studying at JaLS.
After my one week, I find JaLS--with its teaching method, the Sensei, and the supporting staff--to be excellent, and I plan on coming back again.
Among the JaLS' teachings that I find especially valuable is what they called "shadowing". It involves memorizing and reciting a set of short dialogues--dialogues, in the vernacular/casual form, involving situations that you're likely to encounter often. Now, when I speak to Japanese people, I use (with slight modifications) some of the sentences and phrases from those dialogues.

I studied under three sensei during my week there. All were excellent. All were approachable and receptive to your questions--whether during class time or during break time.

A final point that makes me want to return to JaLS is its support staff--your point persons for everything relating to JaLS. They've among the most friendly and helpful staff I've ever encountered. Sayakaさん, in particular, made my stay in Hokkaido especially enjoyable. She helped me with suggesting what to do in Sapporo, finding a good maid cafe, directing me to the best Hokkaido ramen place, etc.. And she follows up!
Go ahead and give JaLS a try. It's great!
