MONEY THINGS:
Tipping: Gratuity not required, anything up to 10% is nice to leave for a particularly good experience. Check to see if service charge has been added already.
OTHER TIPS:
Go to museum at free time of day.
Menu del dia
Bus / metro for transportation
Tax free shopping. When shopping, bring your passport for VAT tax back. Show a picture of passport & they give you reeipt. At airport, give receipt to VAT & they give you the tax back.
Phone: Esim from Airalo. Phone line must be unlocked - AT&T locks their phone lines so can’t get service anywhere else. Call to see if you’re eligible to unblock.
CASH
Don’t need much in Spain! Use Apple Pay.
Get euros through your bank — not at airport (bad exchange rate).
Madrid / Barcelona: Use Apple Pay (!!) Take a bit of cash, 1 credit card, phone, passport. Leave everything else. Never leave with everything in your bag.
THEFT:
In front. Closed. Zipped. Latched.
Bag that closes (zipper / latch)
