This was our first trip to Marco...we went with our friends "repeat offenders". We stayed at the Marriot and it was lovely. Big rooms and we were extremely lucky to get an oceanfront view (we saw two weddings from our terrace). The sand is white, never gets hot and it is only shelly right before you enter the water. The water is very calm and you keep going and going and going and it takes a long while just to get waist deep which is good for "babies" like me. Water is perfect for kids. Daughter and hubby did the wave runner and loved it...I just lazed around and loved that too. WARNING- the sun is very intense...I am one who "does not burn" (rolls eyes) and started out with sunscreen 30-went on to 50-then 70 and then went for the kill with SPF 100 (I didn't know there was such a thing). Especially for back areas and chest - you will need the high numbers there. We rented Chicki huts for a couple of days which was very nice and helped with the sun. We got some pretty shells. We ate at Quinns (expensive nothing great but on the beach), hotel buffet (loved but expensive), -Nene's was the best for breakfast and I also liked Chef's Express which was quirky with "sweet pea" running around and the owner very friendly. Hoots for breakfast was a disappointment and I don't get what the fuss was about..it was just average. Verdis and Stan's were closed as was LIttle Bar. We drove to Naples and ate at Chops which was great and another night Roys (very mediocre but the souffle was to die for). Da Vinci was another winner - we ate there twice. Pelican Bend another hidden gem - friendly service, big portions and great food. One night we went to Cathy OClarks because it was a storm and close to the hotel. Would not go back. Went to the Sand Bar for lunch and it wzs "good" but truthfully I don't see how it is rated #4 on Trip Advisor. The beach is warm warm - sometimes like bath water. A lot of the days you see clouds, hear thunder but most of the time it didn't "hit our hotel and didn't rain. When it did rain it usually rained like the rest of Florida around 4-5 o'clock. I overpacked and brought too many shorts because you live in your bathing suit. It was very enjoyable. I wish I was there now.
