We had our honeymoon in Seoul, S. Korea. We did not book for land arrangement because it's manageable to do it on your own. It's my third time so medyo may idea na ako on do's and dont's. But if you really want to be stress-free, you can do land arrangement. Kuripot kasi ako, backpacker ako before

We went on a winter trip.
Here's some of the places and activities in our honeymoon:
Changdeokgung palace (may free English tour and secret garden)
Hanok (traditional korean houses) Village (beside Changdeokgung) - you can book a stay here; this is an actual residential area
Tosokchon restaurant (try their Samgyetang/ginseng chicken) near Gyeongbokgung
Namsangol hanok village (like a park)
Myeongdong - shopping
Dongdaemun - for young generation mejo pricey shopping area pero fashion forward dito
Namdaemun - pasalubong spree; cheap chocolates and local chichiria
Insadong - cultural, artsy shopping street, food trip street - walking distance from Jongno
Trick eye museum in Insadong
Nami Island - book your trip in Insadong para hassle free. Bus stop is also in Insadong
WINTER ACTIVITIES
Jisan Ski resort for snowboarding/skiing -- go to their website; when you get to the hotel, ask the front desk to call the resort for details on the bus and to book you for the bus. Only Koreans can call them. Cost of snowboarding gears, lockers, ski lift fee half day around 3k-3500 naka discount sila lagi with Citibank so dont forget your credit card. Consistent yan for my 3 visits
City hall Ice Skating - mga around 75 pesos per hour to with gears and lockers na

ang mura yes!
IF YOU STILL HAVE TIME, visit Jeju Island. If you book like months ahead, you can get 80% off. This was not part of our honeymoon kasi 5 days off lang pinayagan samen sa office (meh) but my first visit here was really great. and this is their honeymoon spot.

For nature-loving people. and lakas makahollywood ng feel ng some parts of this island. amazing amazing experience
Hotel: Hotel Rian in Jongno. Very near the subway (Jongno-sam-ga station) and bus stations including airport bus stop kaya very good tong location na to. Best of the 3 accommodations I tried in my 3 stays. Good rooms, good service, English speaking front desk. Around 2k-2500 per night in Agoda
