If you need to leave your BP alone for the vacation and cannot find someone to check in on him then the 3 biggest things I can think of to address are making sure
-that each of the enclosure's heating elements are controlled by a quality thermostat (and maybe a redundant back up).
-that each enclosure has a big enough water dish that will not dry out in 15 days (or really even come close to drying out)
-that the enclosures are freshly cleaned before you leave.
