I’m planning a trip to Thailand with my girlfriend in October/November and am wondering what some must see places/towns are?

I am planning a trip to Thailand for a sabbatical/adventure/holiday and want to know how safe it is to do so alone.

I am planning a trip to Thailand from California for a 14-day trip. I’ve got the hotel and airfare already covered. The tour also covers breakfast. So I was just curious how much would lunch and dinner normally cost per day on average so I can calculate how much to bring to cover the cost of meals.

I am planning a trip to Bangkok, Chiang Mai and Phuket. I am curious about the public restrooms in Thailand. If they are clean, have actual toilets or have toilet paper.
The reason I ask is I went on a trip to China and their public restrooms were pretty horrendous. They rarely had actual toilets. They were usually horizontal troughs or urinals built into the ground and you have to squat over a hole that usually had no flushing system, urine all over the floor, an overwhelming nauseating stench, sometimes no stalls or doors and of course, no toilet paper! LOL
So I’m curious if Thailand has a better system.

It’s the kind of question I ask when I’m curious about something…..
