You can take bus 600 from Jeju airport and stop at Jungmun tourist bus stop (u can use the T-money card). After getting off the bus, you will come to a cross road, cross over to the gas station, then cross the road again, now the gas station should be on your left hand side (you should be able to see the hotel from the bus stop). It is abit of an uphill climb to the hotel. We did see the ocean but its quite faraway. If you don't drive like us, we suggest to only stay a night (we stayed 3). Jungmum resort is quite boring, the attractions are quite dated. The beach is ok.. There are several eateries, starbucks and a newly opened Mcdonalds nearby so no worries about food. The staff we met knows only very basic English (we tried to get suggestions to other places of Jeju by public transport, in the end we just lazed around the area). The breakfast is very limited, and by that i mean if u go after 9am (breakfast ends at 9.30am), you might only get bread. There is only basic coffee, tea, white bread (butter & Jam), cereal & Milk, banana (i cn remember the menu, even after a few weeks that is how limited it is.) There are 2 massage chairs beside the gym (good to kill some time).
