Hi Carole, I moved here from Vegas (Green Valley). My original visa was the 6 month multiple entry I got from the Thai Consulate in Los Angeles (

). They make regular trips to Vegas as well, usually to one of the Temples in NLV. I was not asked to show any financial or flight info for the application but I did have it ready.
As was mentioned earlier, you can do visa exempt arrivals. Or add a re-entry permit to a single Entry visa.
In the end though, if you have a question about what you see on the application...call the consulate and ask their rules. They vary from place to place and tend to change. The LA consulate staff are nice and speak English. There is also a honorary consulate in Portland staffed by Americans that is super easy to work with.
Save travels!
