Bill D We are retired and live full time in what use to be our beach house on a canal that leads to the bay in Ocean City Md., however, more information on your status would make it easier in answering your questions because your needs in a vacation home at least IMO are different then a full time resident. For instance do you have children, do they live at home or are you empty nesters. Are you ready to retire or are your retired. What other hobbies do you have besides boating. I asked these because I believe your approach could be different depending on your scenario.
For instance we first bought the land then built a small 3 bedroom A frame vacation home with a deck, however we made sure we had sufficient land to add on an addition and a two car garage. We did add on when we made the decision to move full time to our vacation home. Now what I would not give up are bedrooms, at least 3 or 4 and two or three baths one of which is your master bath. I like open space so we have an open floor plan for our downstair living area (dining , living and kitchen). During the renovation we did convert part of the deck into a small year round TV room that works great for my wife and I. We also converted what was our bedroom into sitting room adjacent to our new large Master Bedroom on the ground floor. We do have an upstairs bedroom and loft however it is for guest as we seldom go up there. As you get older you just don't want to climb stairs, save your energy for more important things like asking, hiking, walking etc.
The answer to the kitchen IMO is it depends. I am not a believer in a big kitchen even though I am a damn good cook and baker and spend a significant amount of time in my kitchen. What is important is to have it organized so every thing is close by when cooking. I do have an island that I also use but mostly I am in the corner between the sink and the stove. Oh by the way only those items I use the most are on the counter Mixer, Alex Duetto Espresso machine, coffee grinder, vitamin and some other stuff. My other equipment is either on a cart or on shelves in aback bedroom.
A good size deck especially if your first floor is above the water like ours. Our front entrance is at street level however the back is about 10 to 12 feet above the canal so if you grill and BBQ be sure to have the space on your deck unless you like running up and down steps. Our back deck has four grills and a table that sits four. As we are on the water I see no need for a pool and besides many developments have a community pool. As to square footage just remember the more you have the more it takes to clean. My point is big houses are nice but 2 to 3 thousand is definitely more then sufficient especially if you are empty nesters.
As to the yard less is better as to who the hell wants to spend time cutting grass and besides weeds stay green in droughts.
One more point choose carefully your view. Be sure to maximize the water view from your master bedroom and living area. Anyway I hope this helps
