I'm surprising my husband with a vacation to Europe this fall (end of September-first week of October. I am ready to purchase our flights (Open Jaw) and begin the process. I have NEVER been to Europe so I'm a little overwhelmed as there is SO much information out there. I'm looking for suggestions from people who have done it before. I know it'll be impossible to do it all -- there is just so much I want to see, but I want to try to see London, Berchtesgaden (my husband has mentioned the Eagle's Nest before so this might be a good surprise), Paris and Rome. We will be flying from IAH in Houston, Texas and just want to know where we should fly first. Perhaps London and work our way south or vice versa? I'd would appreciate any feedback/help/opinions. Thanks in advance.
UPDATE: I've searched for airfare to London (Heathrow) from Houston (IAH) and it's $1300/each one way. Does this seem reasonable to you? I was hoping to pay $1500-2000 total (for both of us). Any feedback on this would be appreciated.
