Today's diary : Travel plans

My family and I have been talking about taking a winter trip to Japan in December, maybe during the Christmas season.
I actually wanted to go to a Southeast Asian country such as Thailand or Vietnam because I haven't been there yet and it would be a totally new world for me. But my mom has been thinking that it was such a shame that our last family trip to Japan few years ago was too short (it was only 2 nights and 3 days) to fully enjoy. I admit I was too young at the time so I remember only a few parts of it. And because a lot of travel agencies in Korea are offering special deals on flights and hotels in Japan nowadays, I think it's almost decided that we will go to Japan. I am working harder to help earn money for the trip. It's been a really long time since we've had a family trip and my mom hardly has any opportunities to travel abroad. I hope we can make it.

Today's diary : travel plan

My family and I have been talking about having taking a winter trip to Japan on in December, maybe during the Christmas season.
I actually wanted to go to south east Southeast Asian countries such as Thailand or Vietnam, because I haven't been there yet and that it would be a totally new world to me. But my mom has been thinking for the past few years that it was so such a pity that our last family trip in to Japan a few years ago was too short(it was only 2 nights and 3 days) to fully enjoy it. I admit I was too young too as well so I remember only only remember a few parts of it. And because a lot of travel agencies in Korea are offering special Japan flight and hotel deals nowadays, I think we are almost decided already to go to Japan. I am working harder to help with the money for the travel travel expenses. It's been a really long time since when we had a family trip and my mom hardly has a chance to travel abroad. I hope we can make it.

Just a couple of notes...You do still want to go travel to Vietnam or Thailand right?  I see that as more of an ongoing condition that a past event, so I changed the tense on your sentence, but it is only a suggestion.

And jabberoc changed "fully enjoy" to "enjoy fully" which is correct.  But it is also correct to say "fully enjoy it" and that is how I would say it.
