I noticed that I find myself overly rationalizing travel, so maybe that's a good subject. For not quite 3 weeks.
WHAT DID I OVERLOOK?
EDITED from the fine comments from the RS community
Airfare: $712 (IAH to BUD round trip in March)
Gas to Houston to catch the flight and back: $40 (yes, this would be $130 more if I used the IRS number instead of gas cost)
Parking off airport in Houston: $100 (20 x $5)
Accommodations: $0 (i have an advantage on this one; figure $1200 for a nice AirBnb)
Airport Transfers: $50 (public transportation would be about $5, the shuttle about $15 round trip)
Public Transportation Card: $30 (month pass)
Food $400 (things are cheaper in Budapest, but I tend to eat a bit better too)
Entertainment: $120 (thats about 6 concerts or shows)
Booze: $300
TMobile International Plan: $50 (month)
What ever I forgot: $200
COVID Test: Free
Total: $2002
Turn the heater down to 50F (wish it went lower): -$50
Not driving my car for three weeks: -$125
Food -$400 ($20 a day)
Entertainment: -$60 (dont get out much at home)
Booze: -$300
Dining out nice: -$300
COVID Test: $25
Total: -$1200
Cost of Trip: $852
And if I didn't already have a place to stay, a nice Airbnb would set me back about $1,200 or less than $2,000 total for the trip. Of course I travel alone. As a couple, you make out better my guess is $1300 to $1500 per person with the AirBnb cost included.
Sort of unique to this trip is a minor surgical procedure I will get done in Budapest. Not covered by my US insurance; the savings is right at $4000.00 Figure that in and ..............
