Non credo ma alla reception biglietteria, credo si possa chiedere.Credo di aver sbirciato un angolo con armadietti, ma più per mettere uno zainetto.io il mio me lo sono portato con me quindi non ne sono proprio sicuro!....mi spiace

Non mi ricordo di aver visto un deposito bagagli ma anche io confido nella cortesia maltese

As far as recall, and I wasn't looking at it from the same perspective as the question, the general circulation was pretty manageable, but moving about inside the ruins a little more intrepid. Worth seeing though, since it sets you in a place in history alongside the Nile Valley on the one hand and Stonehenge on the other.

Not sure on this one .Check with the web site. details .Bus access from airport passes site hourly.

We took a public bus, and there is a bus stop right outside the temples. Entry was approximately €10 per person, and we just turned up (September 2018).

I can confirm that the tower is not open to visitors, or at least it was not on my visit in 2016 and was not looking as if any change was anticipated..

Hi. We went by public bus and it dropped us at the end of the entrance road, about a 100 meter walk. We actually went with our suitcases so we could go directly to the airport rather than go back to Valletta to collect them and there were lockers with keys to store them in. We arrived well before opening time and had the place to ourselves for more than an hour. That made the whole visit much more special. Enjoy.

we used the buses that go out from the main bus station just outside the main entrance to Valetta, you can travel almost anywhere, its cheap and you can buy a day ticket or one that will do up to 15 journeys I think . the driver scans it. the hopon-hop off bus goes to the Temples and so do the ordinary bus services

We took the audioguide, stopped for coffee at the the very nice cafe and it took about 21/2 hours to do both sites

You can buy the tickets at the place. No need to buy them previously. Maybe only at the special fest, which is when the sun goes down on a special angle every year, and it shines the temple the way it was built for, But this is for one day of the year and it's at the middle of June, I think.
