Clearwater/St Pete

Where is a good (cheap) location (maybe on the beach) to re-new our vows? Any suggestions?

We are high school sweethearts and have been married for 11 years now. We have been through 2 deployments with the Army (Bosnia, Iraq) the birth of our son 8 yrs ago and 5mo ago the birth of our daughter who was born with half a heart.
I would really like to renew our vows after all we've been through and think its time. We are so blessed to still be in love... and I want everyone who has came into our lives to share it with us.

Thoughts, suggestions?

Trying to do this on a budget with the obvious increase of medical bills lately  lol.. thanks!
