Malta (Isn't listed for Europe)

Hi Nick; yes we have driven on the Left in England, Scotland & Ireland as well as St. Lucia in the Caribbean; can't be any worse that there! Thanks for the heads up about getting a car near Valletta, may have to reconsider. Is it easy to hire a taxi for the day for the 4 of us at a reasonable rate. A car rental is cheap between 2 couples so thought we'd do that until your reply?
Thanks,
Jean

I'll second the idea that Valletta itself would take at least one of your two days. There are tons of interesting WWII museums, as well as a few other interesting sights, including St. John's Co-Cathedral, the fort, and the Upper Barraka Gardens

The bus system is very easy to use, so if you'd like to head out to Rabat or Mdina I'd suggest the bus. Route 50, among others, runs between Valletta and Rabat. https://www.publictransport.com.mt/en/ The public transit site is really easy to use and I used my phone to help me find the nearest bus stop and route to my next destination (I went to Ta' Qali craft market, Mdina, Rabat, and the Dingli cliffs all via bus all in one (long) day all using the bus).

Another suggestion for your second day is visiting the Three Cities across the Grand Harbor by utilizing a Rolling Geek (http://www.rolling-geeks.com/). It's a little golf cart-like car that navigates you around the Cities and gives you a tour while you drive. It's a lot of fun and the team at Rolling Geeks is super helpful. You can stop, get out and have a drink or go into a shop, all while you have the Geek. I stopped for a good half hour at Smart City to enjoy just sitting on the rocks by the sea. Take a traditional dghajsa boat (die-sa) across the Harbor to get to Vittorioso (one of the Three Cities). It's 2 euro per person and very fun.

And one last suggestion is taking the ferry to Sliema for the day and enjoying the beaches. I didn't go to the beaches so can't recommend where to hang out, but there's a lot of options at the hotels in Sliema (it's across the harbor on the other side of Valletta). Or take a 75 minute harbor cruise or all day, circle the island cruise from a company like Captain Morgan Cruises http://captainmorgan.com.mt/round-malta?l=1

I loved my few days in Malta so feel free to ask any other questions you have!

With less than 2 full days, it's not worth it. You'll likely spend all your time tied up in traffic and looking for parking. The sights in Valetta - possibly with a bus or taxi to/from Rabat/Mdina (walk between them) will easily fill all your time.
