Mens & Womens freestanding bath hvac

We are constructing Mens and Womens freestanding outdoor bathrooms and are struggling with what type of hvac.
This is a frame/hardiboard +- 150 sq ft structure, +- 75 sq ft per side. Our old bldg (torn down) just had baseboard heat to keep from freezing in winter. (Loc. upstate SC, up to 100 deg summer and down to mid teens at night a few days in winter) We would like to have heat and air in the new baths on a max budget of +- 1500.00. We would also like the ability to cage the thermostats if at all possible. Bathrooms would sometimes go a few days with out being used, but sometimes used frequently on weekends. People have a habit of jerking a thermostat up/dn where it will run for days unattended. If we could get even 80 deg in mid summer and 55-60 in winter indoors that would be enough, but we have to keep the pipes from freezing in winter. We would like a mini split system but the dual zone ones are pricey, and for 2 single zone ones we believe the spaces are too small, maybe causing the units to short cycle? Have even tried to figure out a way to have one single zone unit serve both sides but no one has a practical idea how to duct etc yet. Other options are hotel style units on both sides ((PTAC's?) or just window units that heat and cool or window A/C and baseboard heat??? But we lose control over the power bill if we cant cage the thermostat.
Any ideas/opinions would be appreciated.
Thank you very much for your time.

hotel units seem appropriate. there are thermostat options available to program setpoints and schedule and also lock out user input.
