Recurring (recurrent) training, is super important, especially for IFR, complex and helicopters. Good instructors can always see things you may not in contrast to self evaluation. The FARs are lenient, don’t allow your skills to erode with minimum standards.
My residence is close to PHNL in downtown Honolulu and we normally fly with Mauna Loa Helicopters on Lagoon Drive. Highly recommend MLH:
Please see video of typical Honolulu R44 flight video:
However, yesterday I decided to make a day trip to Kona (Big Island) and fly with Mauna Loa’s main school. Using frequent flyer miles from Southwest Airlines I flew into Kona @ 09:09 HST (30 minutes from Honolulu) then ...flew with the chief instructor (who is an excellent individual and instructor) for (2) hours and then flew home @ 14:30 HST.
Some noted differences between
Kona (Class D) vs. Honolulu (Class B)In Honolulu to get to the practice area requires a lot of work:
1) Clearance to depart Bravo
2) Generally hope that Tower can get you out in between the big iron, military and plethora of tour traffic.
3) Clear Bravo and then fly North of Pearl Harbor in a round about way avoiding the PHNL ILS into Kalaeloa (Barbers Point NAS)
4) The Kalaeloa Tower generally has a bad attitude compared to Kona International for some reason?
5) Then reverse the process back to home plate @ PHNL
It’s good practice for primary students.

In contrast, Kona the practice area is literally adjacent to the MLH helicopter pads:

Just wanted to practice autorotations, governor off, hydraulics off and run on landing on this initial trip. Very convenient practice area and less expensive than PHNL Class B for those limited maneuvers. Southwest is offering inter island for $40 one way. Which is less than half of Hawaiian Airlines. The tower at Kona is the most friendly ATC I have ever flown with. Even with mixing big iron, military and tours.
Overall, I must say, traveling across the island chain for the day and training was WELL worth it!
Tips: bring sack lunch, long sleeves & pants, hat, sunglasses, small tube of sunscreen (TSA friendly), camera, headsets, logbook. Kona is really hot and humid! And if you like, stay a few days and charter a boat for Marlin fishing. Or check out the volcano etc....
Aloha!
