We'll be arriving in paradise at the beginning of July & will be bringing our slightly elderly dog w/ us this time. The concern is if a power failure would occur while we're at the parks. We've been there enough to know that power failures in the loops are rare, if darn-near non-existent, but we still have concerns. We've thought about remote temperature monitors that can be accessed by smartphone but those seem a little expensive. Anyone have thoughts on this...
