My wife and I live in Korea and were looking for a cheap staycation. We got a reservation at this Holiday Inn Express for only 60k KRW. What we didn't realize was that there is no hotel parking, much less to say free hotel parking. (The IHG app just says "Parking:" but it would be clearer if it said "Parking: None".
The parking lot just next door to the hotel costs 50k KRW per night!
When we asked the ground floor hotel staff about parking, they basically just shrugged their shoulders and smiled.
We ended up getting lucky because a friend was able to lend her work parking spot to us during that weekend night.
Pro tip: However, *IF* you're checking in around Sunday noon, and need cheaper parking, there is a small "GS Times" parking lot (~20 parking spots?) next to the 7-11 next door to "Jin Jin Ga-yeon" (Google Map it, it's a Chinese restaurant), which is about an 8-minute walk away from the hotel. It's only around 20k KRW per 24 hours. On Sunday late morning there were plenty of empty spots available. (You can get an idea of the parking lot if you Google Map "Jin Jin Ga-yeon", drag the yellow Google man onto the map, and search for the 7-11 next door.)
Aside from this parking issue, the hotel stay was cost effective. Our standard room was a bit small, true. But otherwise, very clean, English-speaking, great location, a 5-story mall in basically the same building, including a swell & chill (but a bit plain) 7th floor rooftop cafe with an outdoor 360-degree view of the city.
A great hotel stay especially if you are traveling in by metro/bus/taxi. But if you want the convenience of parking next to the hotel, this hotel should be compared to other 110k KRW (per night) hotels nearby (e.g. the Amanti, which has a pool too).
