Sharon & Debbie, we just got back from our trip on Monday night. There were 22 in our group, really nice mix of people, everyone got on really well. Some of them had been away with Just You before and some were on their first solo trip, they all said they enjoyed the experience so hopefully it's given them the courage to do more trips.
I think you will probably both be in a different hotel from us. Because it was early season, we stayed in Minori which was over an hours drive from most of the excursions so we had very early morning starts every day! You might be staying nearer to Pompeii? Can't fault our hotel though, the rooms were kept clean everyday and the staff were really great. Some odd food combinations in the evenings but that just added to the fun 😉
If you do end up on all the excursions, it's definitely a full on holiday.
The walk up Mt Vesuvius is hard work, there's a couple of places nearer the top where you can get drinks, limited snacks and souvenirs. These are also the only places you will be able to get some shade from the sun!
Capri was nice enough although very windy the day that we were there, don't wear slip on shoes if you are thinking of doing the chair lift! 😉 It's an amazing view from up there but other than that, I'm not sure we really got to see the best of the island. We didn't really have a lot of time there to look around and some things weren't open early season.
It's definitely worth doing Herculaneum and seeing how it compares with Pompeii.
Ravello is a lovely area to visit and would have liked a bit more time there. A couple from our group got the bus there seperately on one of the days when they weren't doing an excursion.
The Amalfi coast really is one of the most picturesque places you can visit, very glad we had our amazing coach driver though going round all the winding mountain roads!
I don't know if you'll have the same guide that we had but if you do have Silvia, tell her she's as mad as a box of frogs, she likes to learn new English phrases ;-)
