I bought our voucher from Deal Grocer weeks before our vacation. After many comparisons to other websites (Agoda, Trivago, etc.), Deal Grocer still has the cheapest price.
I searched for areas to visit but it all led us to malls, which obviously isn’t something new. We then just spent the whole day at the hotel, swam for a few hours (it was cold!), had dinner, put the kids to sleep, and (my most awaited part) Kdrama with my husband with beers and chips. Isn’t it perfect? Everybody’s happy!
