Ya...I also think its not a good idea if you just go alone. You better join the package. Don't even think English can communicate with Korean. I live in Korea but my Korean just so so...when I want to ask something in English, they just pretend like they don't know, the Korean people if they have well-educated, they're good in reading English but not speak. If you meet someone speak English well, most of them were study in other countries before. So, travel in Korea....the most important problem is language.
And I can suggest some place you go like you mention at your question. But not suggest you go to skate if your alone. Most of skate restore is far from seoul, the close one you need to take about 1 & half hour bus but it just a small one. If you want shopping...the most popular place of course is 명동 (明洞), cheaper thing you can go to 동대문 (東大門), brand product you can go to 압구정 (狎鷗亭) or 청담 (清潭), outlet you can go to 문정 (文井洞), hip hop product or fashinon wear you can go to 이대 (梨大) or 홍대 (弘大), if you want electronic product must go to 용산 (龍山).
And about you want go to the park like Lotte World you can by MTR and get off at 잠실 (蠶室), then you can just walk to the Lotte World, its one of exit of MTR.
And other place I think must go is like 남산공원 (南山公園) and NamShan Tower, if you have time you can take a train about 3 hour go to 춘천 (春川) or 남이섬 (南怡島)...this two place is the famous place for the movie you always see. Or if you want to see your lucky to meet movie star or not...you can try go to 여의도 (汝矣島), it have many movie company there...I sometimes saw movie star there..ha ha !!
Anyway...hope you enjoy your trip !!
