We took the tender into Great Stirrup Cay - we had booked a clam shell the first day on the ship and were glad to have some shade - there isn't much by way of trees. The process for tendering was slightly disorganized -with an "excursion" ticket we were supposed to have priority boarding but that was only true for the first trip out - after that it seemed to be a free for all - people who had numbered tickets (picked up early in the morning that day) were called to tender locations and then we stood in a very long line mixed in with them. When the next set of numbers was called the new people just jumped the long line causing lots of frustration and confusion. When we questioned the higher numbers boarding before us we were told "you missed your call"... More crew members along the line would have been more helpful but we eventually got there with no bruises.
We were not bothered by any construction as other posters have mentioned - we did hear some hammering and big machines in the distance but nothing that was disruptive to us. Signage was not great and it took us a while to find out how to get our clam shell waiting in the wrong line once or twice but once we found the right place we were set up quickly. Overall the island was very clean and welcoming with lots of activity going on - the Nickelodeon gang was running activities for the kids beachside, and the buffet had a decent variety of foods - again not great but adequate. Again water was the only "included" choice.
Tendering back was easy as people left at different times. Back on board the pool was busy as people returned from the beach.
Since we did not book an excursion we "slept in" and went to the buffet for a later breakfast (around 9:00 am). We left the ship and headed into the town to catch the #10 Jitney to go to Cable Beach. It's a short walk from the pier - maybe 10-15 minutes depending on your load and kids and the cost is $1.25 per person - exact change is needed. Thanks to the info on these boards, we headed to the Sheraton for the day - as mentioned earlier the "kids and grand kids" are not beach people so we found something for everyone. It takes about 30 minutes via the bus. $25 per person bought us use of the facilities which included a large heated pool, two other areas with shallow pools and waterfalls, activities like volleyball, ping pong, etc and use of paddle boats and kayaks as well as towels, chairs, umbrellas and a beautiful beach. There was a "hippo" slide like on GSC also for an additional fee which was disappointing - for what we paid we felt it should have been included but we had a great relaxing afternoon - the waters were a bit cooler than we hoped but we had fun. There are some straw markets on the beach and the kids got some souvenir items to bring home - haggle the price and pay what you feel is appropriate. Headed back to the ship around 3:00pm - chose to take a cab to be dropped right at the port as the kids were very tired - twice as much as the Jitney for all of us but less walking. Back in time for a snack and some pool time before sailing. We did not take the time to look around the port but saw some nice shops and a lot of hair braiding vendors.
