“Activiteit geboekt, was voor de dag dat ik geboekt had. Hier kreeg ik tijdig een bericht van. Ik heb het verzet naar een andere dag. Eenmaal aangekomen was er niemand aanwezig, met moeite de contactpersoon te pakken gekregen. De boottrip ging weer niet door want zij vind de plekken nu niet mooi en heeft besloten te komen de tijd niet te varen. Echter kan je het nog steeds boeken. Het is heel mooi weer nu. Dit is zeker geen aanrader en ook jammer dat het zo gaat want als ik dit had geweten had ik andere dingen kunnen plannen of boeken.”
