tips on vacation photo

will be on honeymoon in Australia with my wife at the end of the month.  Oz is known for some spectacular landscapes and I will be bringing my tripod with me so I can capture lot of shots with me and the misses

in past I have tried shooting with a remote at smaller apertures F8-11, center focus/auto focus with face detection, but nothing seems to correctly achieve simultaneous foreground (people) and background focus.  I understand there is the hyperfocal distance to consider.... would like some tips that will ensure more keepers, thanks

I'm shooting a 5n and mostly with the sigma 30
