with regards to two couples traveling together, our first cruise on the inspiration, was with a couple first time cruising too.... we DEBATED.... DEBATED several excursions.... all trying to please each other...... during the cruise hub and I met a Great group, well several groups and included our friends.... they were less outgoing... by day three, they chose a different excursion, due to port changes... we eventually became comfortable going seperate ways.... along the way... setting up meeting times to do more together as well as seperate on the ship too.....
I know how you're all feeling and trust that you'll feel more comfortable and speak your minds when the time comes.....also.... because this is a long time friend of yours... maybe the "guys" need some time to themselves too.... there may be a bit too much pressure for girl time with the husbands, one having differet interests... the guys may surprise you... or you might try this tactic with the "nude" beach
enjoy and have a snazzy drink for me
