For a touching post on a simple but wonderful San Francisco honeymoon (total cost $2567 including airfare and hotel for a week), see Forest on Finance's The Cost of a Honeymoon.
A quick rundown of the week's costs and the sights:
Monday - Fisherman's Wharf/Pier 39, Chinatown, Nob Hill (Alcatraz tour $66)
Tuesday - Ferry Building/Mission District (Pancho Villa Tacqueria, $22)
Wednesday - Sausalito (rented bikes, $54)
Thursday - Armstrong Redwoods Preserve (FountainGrove Inn, $99 deal on TravelZoo)
Friday - Wine Tasting / downtown Sonoma (Benziger tour, $30)
Airfare to San Francisco: $397 + $31 baggage fees and the red eye back to Minneapolis: $249 + $40 baggage fees.
I say: check it out.
