I think if going as a family, a standard would be nice to have everyone using the same gathering spots for kitchen, bathroom, and entrance. But when I often travel with extended family or friends, I prefer the lockoff - it allows us to occasionally split off or keep our own schedules - they have their own entrance, can close the separator door, have a kitchenette so the early people and the late people can have their own spaces, yet with the door open we can all be together when we want. Another perk if you're traveling with people from very different climates - those that want cold AC vs those that want it warmer - the lockoff has separate AC controls.
If I wasn't doing a near-HH room I'd definitely try to score one along Peninsular Road - 27-29 are only a little farther from HH than the 23-26 loop, but are not in the near HH category - still an easy walk to HH and main pool, still on the first bus stop, but if you miss a bus, you can easily walk over to HH bus stop and catch it since that's the last stop. 62-64 are also nice and close options to HH.
