Hotel
Centrally located hotel in "gang-nam" (means South of the Han River), near many key neighborhoods to visit like Garosu-gil, Apgujeong Rodeo, the Gangnam Station area, and the up-and-coming (!) Seongsu-dong. 12 minute drive to the wedding venue, 25 minute bus ride (Bus #9404. From hotel, walk 3 min. to Baengbaeng Junction station. Get off at Seoul Children's Hospital. Walk 3 min. to venue).
Hotel
If you're staying in Seoul longer and don't mind being a bit far from the wedding venue, this is a nicely designed hotel in Itaewon, one of BenJi's favorite neighborhoods for eating, shopping, and going out! It's also in "gang-buk" (North of Han River), which means you'll be closer to the Namsan Tower, great art museums like Leeum or MCCA, Gyeongbokgung Palace, and Samcheong-dong / Bukcheon (another one of BenJi's fav places). 35-40 minute drive to the wedding venue which is about a $13-15 taxi drive.
Hotel
Is this hotel pretty? No. Is it cheap? Yes. I don't know about you, but I like cheap. And it's got solid reviews. 14 min. drive to the wedding venue & 19 min. by bus (Bus #3002. From hotel, walk 1 min. to Raemian Apartment/Financial News station. Get off at Seoul Children's Hospital. Walk 3 min. to venue).
Hotel
Nice hotel near Apgujeong, Cheongdam, and COEX Mall. Would be a good option if you want to spend more time in Gangnam.
Hotel
Slightly on the far east end of Gangnam, but a solid hotel with proximity to Apgujeong, Dosan Park, and Cheongdam.
