2 nights in Seoul, where to stay/what to do - Hilton/Marriott preferred
So we have a stopover on Korean Air due to award "availability" (LOL)
We arrive into ICN on 4/29/20 at 6:20 a.m.
We don't leave from ICN until 5/1/29 at 10:20 a.m. (going to ORD)
So we'll have our luggage from our Maldives trip to tote along. Since it's 2 nights (if I looked at the calendar correctly), I'd rather not stay at the airport Hyatt (although I'm sure it's a fine Hyatt), as getting a little culture (LOL) is good for us.
But I don't want to be on the far end of town either with hours to the airport (I think we'd have to be AT the airport 3 hours prior to depature, so like 7:20 a.m.)
I'd prefer Hilton as I'm a diamond member (but the free weekend cert won't do me any good) or Marriott (free night category 5 and lower? certificate).
Is there something "close" to the airport, but also semi-close to "things to do" for us tourists? LOL!
Obviously we have lots of time to plan, but it'll give me time to research and things.
