Hi Mate,
Last June i did possibly one of the best trips ive done, did it over 2 weeks and had the best time through being able to spend loads of time in each location.
basically, i needed to be there for 2 dates a stag do and a wedding. as expected the stag do kicked off the preceding in Vegas, I wont bore you with the details but Vegas is a must especially as you wont have the little one with you!
The real road trip then started, a rough recap of route 1 went a bit like this;
- Vegas!
San Diego
LA
Santa Barbra
San luis Obispo - ended up at a college frat party exactly like something from american pie!
Monterey
Santa Cruz
San Jose
San Fransico
Then up to wine country
Napa Valley
St Helena
The route went through from the big party places all the way up to the more relaxed and chilled out sides of the states - throughout the trip the people, the places and the wine were amazing! thoroughly recommend it!
Cant think of anything better to do for a honeymoon!
Good Luck
