Thanks everyone for all your words of wisdom!
Yeah- there is a serious drought in Sicily- a lot of residents even posting about it. That said, I did call the tour company and they said if they ever thought the tour would be uncomfortable or unsafe for their clients it would be cancelled or at the very least the itinerary would be adjusted. Nothing going on much with Mt. Etna right now.
I even asked them about- yes- I did- how they handle the toileting stops on the tour. Something we don't think about here in the USA and I didn't not know about how it is overseas. Being it's an issue with us older people. Plus with the water issues in Sicily...They said there is one on the bus but not recommended to use- ok- it's like that here also. Said they try stop every hour. My husband in particular gets worried with this. We try not to drink a lot of water or anything when out and about.
I also spoke with the travel agent. She did not really give me any assurances regarding the horrible flight we have. She said if we were to fly into Rome, for example we would then have to leave the terminal and go through everything again to get on another airline. She said maybe we could do a micro hotel in the Munich airport but didn't give me too many details regarding that and what that would entail.
She did say anything could happen with the flights we have and maybe a change would close that 6 hour layover a little bit. Of course, it could also go the other way and be even worse.
So Friday she is charging our credit card with the balance for the tour and finding out about what we need to pay for the hotel transfer from the Catania airport and will charge that also.
Meanwhile, we pretty much decided we will take two carry ons and 1 checked bag for the overage and toiletries. Lufthansa allows one free checked bag and 1 free carry on for each passenger, plus we will have our two small backpacks. But the tour company only allows one suitcase per client in terms of transfers, so we will have to transfer the extra carry on ourselves.
My husband's carry on is pretty worn so we are tossing it, but my neighbor said she has one we can borrow so I will check that out this weekend to make sure it will work for us.. She also gave us a suitcase that we can check in. It's not real big, but we should be ok with it. No sense on buying luggage as we don't plan on flying for vacations after this. She also gave us a plastic water bottle with a filter. My carry on I've had forever is still going strong.
I also got a head start and ordered a few thing on Amazon and Walmart like an air tag for the checked bag, travel pillows, some personal clothing incidentals. I am thinking of getting an inexpensive collapsible cane just in case I have a problem with my back or leg. We both need a just little bit more clothes as we are not fashionistas, but will buy inexpensive, plain, simple, casual things, and definitely will try to get the best sneakers we can. We usually buy inexpensive ones in Walmart or on Amazon, but I think we might have to get much better ones. I assume we will be in them for the entire trip.
So yes- we are going to still do this trip! As I have said before, the tour seems wonderful. It's just getting there that will be hell (and coming home). The drought and the volcano were just additional things that ramped up my anxiety. The flights are why I do not have that excited feeling like I've always had for our other vacations, most all of which we did independently. Our energy levels are ok, but not what they used to be, plus my back issue. My husband is low energy for the most part. I'm just very self aware of what we can handle physically (and mentally! LOL!)
So, that's it! It's now or never! Appreciate all your input!
