Jiejie, you hit on what is now our chief concern... Time. As you mentioned I'm concerned a week is not enough time for the trip. We would leave on Saturday but not arrive at DSP until late Sunday night. Realistically, that makes Monday a half day and I'm wondering if it's worth the flying if we need to leave on saturday. Missing additional school might be a problem for the kids now that they are in high school but we need to think through it. If nothing else, I'm thinking maybe we just stay in Ubud the whole time.
Thanks for the tips on the bike tours, sounds like exactly our type of activity.
I'm still so undecided on this.
