The dollar vs. the euro is down to it's lowest point in five years since Oct 22, when it was 1.03 vs the euro. It's currently at .85, only a few points from it's five year low vs. the Euro of .82 in January 2021.
Is this impacting your European travel plans? It's tough for us to take an almost 20% hit on everything, in addition to committing to a trip where it's highly likely the exchange rate will get even worse. Do you plan to make other adjustments to compensate, e.g. stay in less expensive hotels, less convenient air travel arrangements, less time away or eat at less expensive restaurants? Or maybe you can afford it and you're going regardless.
Note: The rates of exchange noted above are factual and easily obtained by a simple google search from multiple trusted sources assuming you do not reject what you are seeing with your own eyes.
