Eight people, six flights, one villa. The hard part was never the party - it's getting everyone in the same place with a boat waiting. Tell me the headcount and I'll handle the rest.

Thailand does loud and it does civil, and a good week has both. The trick is knowing which city does which, and not spending the one big night in the wrong place.
Thailand ended visa-free entry for Indian passports. For a group, the e-Visa is the only sane route - one file per person, done before you fly, no cash counter at 2am.
