I found a cruise that would leave Los Angeles and head south and have two stops in Mexico and then head back to LA.

Being on a cruise ship would fulfill my beach requirement for my baby moon.

Concerns I have:
-If we go on a cruise, it will be my first time on a cruise. Pre-pregancy, I do get sea sick and have to take Dramamine. But because of my hyperemesis, I'm currently using an anti-nausea patch and I take reglan and zofran if I have any inkling of nausea. Am I pushing it by subjecting my body to hyperemesis with sea sickness on top?
-Norovirus outbreak
-If something happens to the babies, I will be in international waters and might be hard to get back to the US.

Pros
-I'm looking at beach resorts in CA and some are going for $300-400 a night! Going for 5 -7 days will definitely add up. I found some last minute cruise deals (at vacationstogo.com) that can go on a 7 day cruise from LA for $500 each person and includes entertainment and food. If I go to a resort, we'll have to buy food or consider cost of eating out.

Oh, I'll be less than 20 weeks when I go so there shouldn't be any issue with traveling.

Any other concerns that I'm not thinking of?
