I just realize dif i do a day in ZRH it throws off the next 2 flight, which messes me up for shabbos. unless you think it might be better to spend shabbos in Bangkok rather than Phuket
I would suggest you fly to Samui from phuket. As I've said phuket weather that time of year is unpredictable... Samui is much better. You would need to fly bangkok airways phuket to Samui direct... Samui Chabad house is very nice, and shabbos there is great. Their restaurant is also great and costs pennies.. (almost)
Not sure when you're planning on traveling but it's quite likely things in BKK will be quieting down over the next few weeks, as the government has agreed to negotiate for early elections... but anyway Samui would be nicer.
Thailand has some great shopping!! and hotels there are great.. (check out the JW Marriott Phuket, usually can get for about $130 a night...) There are other hotels which have access to the pools straight from the room (you open the door and jump in to the pool..) pretty neat!
