I looked up some on the internet before the virus. The thing I did not like about them is that they would have you riding tour busses from 8 am to 10 PM almost every day.
Then I would not have any time to go to night clubs or meet women at all.
I have visited Costa Rica and just went on some individual day tours. That way I could have more time to explore by myself or relax at the hotel or beach.
I do not have anyone to go to Thailand with as all of my mail friends who are single are either to religious to pick up women or do not want to spend the money or are frightened by the idea of seeing beautiful Asian women. They are used to bulky domineering western women.
I am not sure how safe it is walking around night club and tourist areas in Bangkok at night. I consider my self somewhat street wise. I do not wear bling and especially while traveling and I wear dull colors and shoes without flashy logos. I also like to act like I know where I am going and not stare up at buildings like a tourist.
I have been to Costa Rica maybe 5 times now.

The worst thing that happened is in San Jose I went to a restaurant about 4 blocks from my hotel. It had gotten dark and on the way back a Toyota pulled up and 2 men were in it. One pointed a gun at me and said " get in the car." I said No. I said "If you want my wallet I will throw it in the car." Then they said something like you Americans come hear to F our women. I pretended that the engineering company I work sent me down there on business and I was staying in the hotel that the restaurant was in. They questioned me about that and I bull shit ed them with details I mad up. Then said something like I do not want to get shot but if you are going to do it I would rather have it happen where I am because there are people on the corner a block away and they might call an ambulance. They drove off without taking my wallet. I have a CWP in Florida that allows me to carry a gun. So I am used to guns. I experienced fear but to a lesser degree although I was unarmed. In San Jose many stores put sheet metal fences and gates with barbed wire on top blocking off the alleys so I could not run down a place that was to narrow for there car to fit in. Although violent crime is lower than the US people put bars on there windows and walls with barbed wire or even razor wire to stop burglars. I have read that 10 years ago tourists would get mugged in the main park in San Jose in the day time an that is why they have a loot of police in the park now.
