yes it's a little bit old and some things would need a refresh, but the geographic situation was great, excellent to walk around and close to the adventure park. Room average from the size as normal in Korea. A little shop, SPA and Karaoke is situated in the base.
Big and nice park outside, must be very nice in Summer.
Bigger bar with live music....however not a really good singer :-)

4 stars just
This is a huge hotel in an area of many other large resort style hotels.
The room safe was not secured in room 727 so anybody could pick it up and walk out with it from the room. We therefore did not use it. I know that South Korea is a very safe country BUT why supply a room safe in a supposed 4 star hotel tourist focused hotel AND then not secure it?
The Exodus tour group check-in was slow but it was a Saturday late afternoon and the hotel was very busy.
The room was clean with full sized towels and a largish bathmat supplied. Neither unfortunately are a given in Korea.
Room heating was a typical constant 25 C even with the system turned off. This unfortunately is the norm for Korea come 01 October onwards. The window can be partly opened. The continental quilt is way too hot and we stripped out just the covers to use as a top sheet. The bottom sheets are barely bigger than the mattress base. Why again in a supposed 4 star hotel?
Only two free drinking water bottles were supplied even for the two night Exodus tour stay. Again not helpful to western travellers.
No sugar or dairy whitener is supplied in the room. This is a too common frustration in even other supposed 4 star Korean hotels.
There is a non freezer equipped, small room fridge. I have medicines that need to be kept at 2 - 4 C so freezing a gel pack for later day travel is important to me. There is no ice machine in the hotel but the front desk were able to take my gel pack to put in an office freezer overnight for me for my post hotel travel day. My Exodus tour guide helped facilitate this.
Fast easy to access, free in room wi-fi.
The bed was softer than many here in Korea. The 2 pillows / bed were firmer but appeared to each be in near air tight plastic bags = unwanted noise and sweaty.
There is a functional shower / bathroom.
A too large and too heavy footstool / seat is in the room. It also has very sharp edges. Why such an impractical furniture item?
The one suitcase raised stand / bench is too small to fit a large suitcase in. Why again? Who designs these supposed 4 star hotel rooms?
We could not turn off the ceiling down light in the room hallway so I had to cover it with black tape (that I carry). We also could not turn off the two lamps on the desk near the TV. So I took the bulbs out of these to sleep. There is a master power control switch BUT using it also turned off the wall power sockets near the beds; and we travel with 2 CPAP machines. Again not the world’s best room design.
The breakfast buffet was pleasing with the pre-cooked hot food actually mostly kept hygienically warm. This is very rare in Korea.
We ate in one evening at the small ground floor restaurant with pleasing and good value meals; but too many little annoyances here overall to rate the hotel higher than just 4 stars.
