So it looks like we've got the plans more of less finished.
1) Crash at the Holiday Inn Hanoi after arriving late, and then leaving early the following morning. 10k HH per room. (The Opera House from Hilton looks very nice, but we'll be arriving and leaving while it's dark, so no point in spending the extra money.)
2) Do a 2 day, 1 night junk boat tour on a private boat in the bay.
3) Spend 2 nights including shabbat at the IC in Hanoi, which is a few minute walk from the Chabad family.
4) Take a 4 night, 3 day trip to Sapa, but not hitting up Bac Ha Sunday market. The 4 nights will be 2 nights on the train, and 2 nights in Homestays, roughing it with the locals. We could do hotels instead, but we want to experience the local living.
5) Fly to Danong, spend 2 nights at the IC, and then drive to Hoi An, stay 3 nights including shabbat at a AirBnB propery in the center of the old city.
6) Spend last night in Hanoi b/f flying back home.
Wish us luck...
