As you are airfreighting your bike into Panama's Tocumen Airport it would seem logical and desirable to get set up for a few days in a hotel close to that airport . That way you could be within minutes of the customs clearing offices and save a lot of time and money over taxi rides from the city center 20km to the west
I did investigate the hotels along the Pan-American highway in the area where it flows along the west and north of that airport , but that was more than ten years ago . There were indeed a number of suitable hotels in that stretch .
If you go on google maps and search for Tocumen>hotels you will get a handful of hits for hotels plus some B&Bs . Click on them and you will get some current pricing and special deals .
Of course it is not difficult to catch a big name hotel at a high price but there are others with quite reasonable pricing .
To wit , the Express Inn PTY Aeropuerto springs out . This hotel would be close to ideal as it stands just north of the main terminals area along side Calle Enrique Malek , the street skirting the west side of the airport .

Other hotels are right along the Pan-Am #1 highway or a few blocks off it . Along Highway 1 are number of modern commercial plazas and enough restaurants and some banks.
