What I would do (others can and will disagree no doubt )
First one - if it can take bigger than a nano giving co-ords to the next stage, then set it as a traditional.
(2 caches fairly close will attract more finders than one on it's own.)
Second - good idea to get people looking around and appreciating the area more. If the answers are to be found near the cache site it's a multi.
(It's only a puzzle if some work is needed before getting there e.g. googling for answers that can't be found there, or working out a puzzle)
Hope that helps.
