Aruba also allows uploading of the negative test result prior to departure...and it allows testing on arrival from those visitors not from high case states (24 of the 50 states are listed as high COVID states)

MPORTANT: Uploading a negative test result prior to travel to Aruba is the only option available to residents of the following US States for being granted entry to Aruba:

Alabama, Arizona, Arkansas, California, Colorado, Florida, Georgia, Idaho, Iowa, Kansas, Louisiana, Mississippi, Nevada, North Carolina, Ohio, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, Wisconsin, and Wyoming.

Residents of all other US States and other countries with whom Aruba’s borders are open will have the alternative option of taking a PCR test immediately after arrival in Aruba, which is mandatory if a negative test has not been uploaded within the required timeframe prior to arrival. The cost of this test is US$75 per person and needs to be pre-paid as part of the online embarkation/disembarkation process. Children 14 and under are not required to take the PCR test.
