There has been an incident happened during my holiday (vacation) the memory card went wrong and I lost half a day’s worth of pictures. Meaning I had to spend another half day retaking pictures on a new memory card, which I brought from a supermarket. I also talked to other photographers around the area.
One said a similar incident happen during a wedding however he caught it early and had a spare memory card.
Another tourist said she was taking photos without realising her memory card was almost full and didn’t take a spare.
To avoid disappointment always carry spares with you like batteries and memory, available at online retail or auction sites. You can take another camera but make sure its fit for use. If the camera is playing up get it checked out in shops and/or websites should be available in the manufactures guides or online.
