I understand the need for a cruise!! I feel that way often. I am doing the med in oct then a TA back to new Orleans.
It is possible that I will try and squeeze in a Carib cruise in sept. if you like I will message you if I find something that fits and is a good price.
Just got your message, though flying to Galveston wasn't on my agenda. Which cruise were you thinking about and I'll will check out the cost on my end.
