Bali honeymoon in august

Hi! Getting married in august and planning to go to Bali for about 12 days in mid august.

We were thinking so far of staying in Ubud/Tegalalang in the tree cabin type air bnbs for the first 5 days and then going to Nusa Penida for 2 nights after that.

The remaining dates from the 18th to the 23rd is up in the air? Should we go to Seminyak? Or where? Any suggestions?

We’re Muslim so don’t drink or go clubbing so night life isn’t a priority. We also don’t want to be in any insanely busy areas

Please give any suggestions of must do stuff to!!

Thanks in advance!
