This is Thailand !
There are rules and people pay good money to break ,em!
You will NOT be arrested for walking around drinking, (cover your drink!) the shops/bars will be ordered for the 13th certainly not to sell alcohol, Im not 100% sure but I cant see em doing so for 3 days as there is only 1 official Songkran Day.
Even on that day, the hotels and restaurants will still sell it. Be prepared to eat 'in house' for 3 days or sit wet in the restaurant of your choice...
If you have to have a lady for the day, organize it the day before, and remember that the day will finsih at 12pm, about the time a lot of you will be fixing on going out for the evening!
You will not get soaked in restaurants...Thais value food way to much for that to happen...
Tips for enjoying Songkran Day.
Sort a more than adequate amount of cash out the day before, then you wont need to visit the ATM/ money changer.The banks will be closed.
Stock your minibar fridge up, now you wont run out of grog.
Acquire your super soaker as early as possible, prices skyrocket on the day for some reason?
Leave any wetables in your room, take out only cash, phone and if you must , a plastic card ALL in a plastic bag ....Ive even seen a Bangla Cop with his gun in a plastic bag...5555
AVOID ingesting the water in ALL cases. The thais arent gonna waste good clean drinking water on dousing you!! Ear and eye infections are easy to contract, my trusty speedo swimming goggles were invaluable last year, some water can hit you at great force.This year Im considering 'Blutack' ear plugs as well as I had a young lady fire a water pistol straight down me earol last year.
Worn out thongs (flip flops) are not adequate footwear for the slippery conditions, nor fleeing a posse of well armed drunken Bgs either.
An open helmet with a large drop down visor would be a useful 'borrow'.
Forget about a cheap raincoat, it just makes you more of a target.
Have plenty of changes of clothes available in yer loom and a jury rigged clothes line would come in handy....
Be prepared for ice filled water, and Prickly Heat powder slapped on you (which when wet kinda burns)
BE CAREFUL OUT THERE PEOPLE!!!
