Spending US Dollars in the US... does my thinking make sense?

I have some rather modest savings... and what will hopefully be a modest wedding in the US in February. Meanwhile, I've changed jobs and will have much lower pay.

I'd initially thought that I should try to keep as much of my savings as possible. Not for immigration purposes - my fiance owns two businesses AND we're getting his parents to cosponsor just to be sure - but because, well, I worked hard to save my money!

But, from what I gather, $1,000 = £564, minus exchange fees. And, from what I gather, that will have roughly the same spending power in England as $564 would have here (depending on what I spend it on.) Doesn't it make sense to just go ahead and spend my dollars on things here, rather than tapping into David's money for the wedding? I will still probably rely on his money, as well, at least for the honeymoon and visa expenses... so, what would be the point of hanging on to my dollars?

whenever possible I pay for $$ priced thigs from my USD bank account and my ££ priced things from my UK bank account.  why pay to transfer over money if you don't have to.

It seems to me that you post is more about how you and your future husband are going to be dealing with money issues than about US/UK exchange rates. 

You are talking about possibly relying on "his" savings so that you can save "your" money because you worked hard for it. I suppose your fiance works hard for his money, too. Have you discussed this with him?  How would he feel about you using his money to pay wedding expenses without contributing any of your own money? Since he would be paying for the wedding expenses, would you be willing to let him dictate what kind of wedding you have?

Have you discussed how you are going to deal with paying bills and so forth after you are married? Once you are married, many of your expenses are going to be joint expenses.

You need to do the 'big mac' test.  Most often, an item you would buy for $1000.00, would also be 1000.00 pounds over here, which means you are actually paying about $1500.00 for something you would buy for $1000.00 in the US. I tend to try to spend my US money only in the US if can help it.

I really don't see how you got this from my post...

I think I specifically said that I would be spending my money on the wedding, rather than saving any of it at all.

He'd offered to pay for more of the wedding expenses, but I realized that it didn't make sense to do that, because my money won't be worth as much after we're married and living in England.

As for money issues, yes - we've discussed them. I'm going to be a housewife/SAHM. He owns two small businesses. For my own "pocket money" I am going to work 16 hours a week at minimum wage in one of his shops. This will give me a sense of having my own money, but it won't cost us anything, as I'll be replacing a part-time employee. I'm still not sure how much of that £82 will be true "pocket money" and how much will go into running the household, but I like the idea of earning my own keep.
