Yo Frank... First of all Congrats to your daughter and Family!!!
Key West is Expensive!! but worth the visit... This place is awesome and centrally located for walking distance to all the "Night Life" of Key West.

it's a historic B&B with 5 swimming pools and garden area for morning coffee & breakfast? I think it was around $260.00 a night? for a King bed with a balcony out over one of the main streets running through Key West.. one morning (around 3-4 am) I sat out on the balcony in my birthday suit smoking a cigar, drinking my beer and watching people stumble on by...

There is Public Beach's, not sure which one we went to, but it wasn't a far drive from the southern most bell spot. both years the beach was dirty with floating Debree. but you can walk the peir and swim. only the beachfront hotels pay to keep their beaches cleaned up. there's a restaurant on the public beach we go to and it has great food!!!

Mrs. and I got Married in Key Largo in June of 21. a buddy of mine that I trained in the military (Air Guard) he came into the unit at 18 fresh out of HS, went on to retire from the guard and as an EMT for St Louis County and was part of the diving team that searches for drowning victums 33 yrs. he now is a Diving Instructor in Key Largo and Capt. of his boat. I got ahold of him to marry the Mrs. and I. we were going to go 13 miles out into International waters for our Vows.. but the water all week was choppy 6ft waves so we got married on a floating Tiki Bar in a bay on the gulf side in Key Largo. and our Honeymoon and Anniversary spot is here:

We inquired about getting married on the beach at this place and they told us we would have to rent out all the cottages.. 32 units? to pricy for our budget... so we did the 90 minute Floating Tiki Bar tour for a couple Hundo's and got hitched in the bay there... LOL Mrs. even got to drive the boat!!! these floating bars are located at a bar/restaurant located walking distance from the cottages. Our buddy Mark as a Capt. can marry your daughter if your needing someone? He's an avid cigar smoker as well... LOL
eventually the Mrs. and I are going to be moving to one of the Key's for out retirement soon...
Hope this helps and again Congrats!!!
