We are doing our first cruise in October. I was a little apprehensive but she was keen and we got a reasonable deal. Starting small with 7 nights from Southampton to Vigo, Lisbon, Porto and back via Cherbourg. Figured no harm no foul for an easy 7 days for the first one. If we like it, we will go further afield in future/longer sailings.
Will the boat be full of old people? That's really my only "concern", along with developing another niche holiday habit - I already ski once a year. Life is going to start getting dear if I like cruising.
It's with P&O who I think might be at the less salubrious end of the market but I'm sure it'll be grand.
