What remains on your angst list?
As illustrated there are a number of members here, each with a nugget or two to share.
Many moons ago, when I was a lad, my first trip to Thailand was supervised by an excellent travel agent. All we had to do was pack and await the:
Taxi from home to Heathrow, sign bearing agents at airports, delivery to overnight Bangkok hotel, two days accompanied sightseeing. Transport to airport and check-in to a domestic flight, taxi to ferry, VIP cabin, taxi to 5* hotel. Same returning.
I am surprised that nobody?, is offering and managing today's travellers similarly.
As you post the first two days you will be enjoying your hotel room, basking in the glow that envelops all travellers who against all odds, reach the promised land of talcum powder covered beaches and sparkling Wats.
Days 3 to 6 sampling the delights the hotel and your companion provide. Don't forget to feed the cooing "doves" on your balcony.
Days 7 to ?, counting down to when that shiny freedom door is unlocked.
All we ask is a new TD thread of your return trip.
