The package details and the redemption address listed on the voucher were incorrect. Early that morning, I went to the Comic Art Center closest to my hotel, showed the voucher, and was told it was invalid and could not be redeemed. The staff said they had never seen a KLOOK voucher, so I had to contact customer service. Customer service instructed me to try other redemption locations listed, including the Choco-Story Brussels, Autoworld, and the Royal Museums of Fine Arts, but I felt this was too time-consuming. Fortunately, the staff at the Comic Art Center kindly asked about my situation, and I informed them that I would try another location. However, the Comic Art Center staff called Choco-Story Brussels to check and confirmed that redemption was not possible there either, telling me that the only valid location should be the BELvue Museum. I then went to the BELvue Museum to redeem the Brussels Card, but about two hours of my time had already been wasted. Furthermore, an issue arose regarding what I originally thought was included in the package details as follows: inclusion of admission tickets to 48 museums, a 24-hour Brussels Card, a free Brussels guide, a free city map, free museum admission along with discounts on tourist attractions, tours, bars, restaurants, and shops, a free information guide, and a museum map. However, the museum staff stated that I only had access to the admission tickets for the 48 museums. Therefore, this was another discrepancy in the information provided by KLOOK. I hope KLOOK will carefully verify and correct this content. Aside from this, the Brussels Card offers great value for money and is very convenient. Upon redemption, you are given an A4 sheet of paper, and by showing the QR code on the A4 sheet during your visits, you can either exchange it for a physical ticket or enter directly. Afterward, within the 24-hour period, I visited the Comic Art Center, Choco-Story Brussels, the BELvue Museum, the Royal Museums of Fine Arts, the Royal Palace of Brussels, the Belgian Beer World Experience, and the Oldmasters Museum. I highly recommend it to anyone who enjoys visiting a wide variety of museums.
