We'll be on the July 7, 2026 Galapagos/Bridges tour. There are 5 in our group, me (grandma) and my son & daughter-in-law and two children girl (11 yrs.) and boy (age 8). We live on Long Island, NY. I'm wondering if we need to get specific vaccinations for Equador. Also do we need medication for high altitudes. I read the CDC report for Equador, but thought someone here may have first hand knowledge. Thanks in advance.
