I am pregnant, which wouldn’t have been an issue as none of the activities were in any way too hard, but being put at the back of a full minibus on a freak heatwave day (over 100F) - with the air con not covering there - was not acceptable. Couldn’t hear guide from back, and felt like I was going to pass out numerous times from heat on bus. Couldn’t ask guide any questions unless off the bus as he couldn’t hear us. Felt extremely sick all evening after finally getting back. Bus should not have been that full during a freak heatwave, and people should have been rotated as a consequence. Really unhappy - ruined the trip
