We leave our US home for months at a time. We leave our car in our driveway, partly as a sign that someone may be home.
We don't sleep well in motels (when we travel we usually rent houses). My spouse does not like to leave our house with suitcases via a taxi as years ago there were a number of house robberies in DC-Metro that were eventually traced to taxi operators (the cabbies did not rob the house but sold this info to thieves).
We live an easy 25 minutes from our FL airport, so the afternoon before (between rush-hours) we rent a car at the airport and return it at our flight time. I usually find $30 - $40 daily rentals with the major companies using my Costco cards (others will have other discount memberships I'm sure); at the holidays I have paid up to $50 for a one day rental. I start checking Costco a month before our travel and then every few days. I am amazed how these rental prices yo-yo, so it's worth a few minutes a day to do this. I have recently started checking Uber but the rental car prices still beat them. Cabs to or from the airport end up between $65 and $70 and that's pre-tip.
When we return to the US, same deal in reverse.
One added bonus is that the rental car drop-offs at many airports are very close to the termina, closer than the economy lots in our case.
