My husband and I are planning a trip to Europe this summer. We've already decided we are going to split out time between Scotland, London and Paris. Any recommendations? Specifically must visit areas in the Scottish Highlands and what area(s) to stay in Paris. We have a bunch of hotel points so we are thinking about using them for 2 nights at a really fancy hotel in Paris by the Opera House. Not sure if we should stay in another area for the other 2 nights we are there or stick to that general area. We are probably going to do a combo of airbnbs, b&bs and hotels and really open to anything!
