Well, I am not running much now, due to injuries that have sort of forced me to stop (I joined DisBoards and created my screen name long before I was plagued with injuries, BUT I do still love to run, just can't run as much now. BUT, my DH is an avid runner, so he will be running a lot on our trip. (he's running a half-marathon this weekend! ). My DH will be running on deck 4 for sure on all the sea days, and on our port days where we don't have a FULL day packed. But, as for running AT the ports, I don't think he is going to run at the ports, unless with one of our shorter port days planned, there is an obvious place he can go run at the port while the rest of us are on the ship. So, I'm sure your DH and my DH will see each other on Deck 4, and I FOR SURE will be on Deck 4. I probably will just be running like 3 - 4 laps only and then just walking the rest. We actually wanted to take Vueling over Ryan Air, but I tried for weeks to book our tickets online, and the website would not let me book (could have been "user error!"), anyway, I just got frustrated with their website, and so booked on Ryan Air instead. But, their prices were pretty much the same, and they both seemed to have the same strict rules, so I didn't feel like I was going to a worse option. But, I do remember Vueling seemed just a BIT less rigid with their rules, so that is why I wanted to book with Vueling... So, I don't have any advice or tips about Vueling. But, I'm sure someone here does.
