Went to disneysea with girls that 10 to 12 years younger than me :-)
Sani was homestaying at one of hippo members, and when her host asked her to go to disneysea together, Sani asked me to come along.
Anyway, since most of the rides are intended for two, and usually Sani stayed with Shoko (her host), most of the time I rode the rides with Maha - Shoko's friend. She's 12 years younger than me (well, almost 12 years younger actually, since her birthday only 6 days differs from mine), however, we still could hold a great conversation - I didn't feel the age gap and so did her (several times she said disbelievingly, "Are you really 29 years-old?" :-) )
One memorable trip...
