This was the most I have ever splurged on a hotel. So I had my expectations high and I was a little disappointed.
The main reason I chose this hotel vs. others on the beach was they had a larger room with a pull out couch. We had three adults and each wanted our own bed. If you are doing the same-do not bother!! When I say I have never laid on something so horrible as the pull out "mattress", I do not exaggerate. It was like laying on springs with a sheet over them, and it slouched in the middle. I lasted about 10 minutes.
In the morning we learned our tub did not drain. When I informed the front desk, I also asked for a new mattress. She was not sure they had any spares. But, the tub was fixed immediately! So that was great, but we ended up having to share beds the remainder of the stay.
I was also disappointed with the breakfast. You can make your own waffles, but the rest of the food is microwavable sandwiches, oatmeal, cold cereal or yogurt with toppings. One morning they had biscuits and gravy, but they were placed in single serve to-go container, so were cold. If you are only staying one night, this would be a good breakfast-but it got old really fast. For the price, I expected more.
The private access to the beach is awesome!! BUT if you want an chair and umbrella, they use a third party to rent those at $60 a day. Again, for the room price I would think that would be included. There are three very well maintained pools, one is a wading pool for kids with bucket drop and fountain. There is an outside bar on the deck above the pool too that was super convenient AND they made milkshakes for the kids. There was only one bartender who worked her tail off....so you will have to wait a bit for your drinks. They also had nachos/hotdogs etc which was nice to tie you over and you were able to charge everything to your room.
If you need to use a car share ride (uber, lyft) don't bother....unless you have an hour to wait. Thankfully the front desk gave us a name of a gentleman who lives next door and provides a shuttle service. Super great guy and very convenient. There was also inconvenience of having to go to the front desk every time we needed something like more towels.
And finally they charged me double. When I called about it, the person at the front desk argued with me but eventually gave me to a manger who did fix it and refund me with no apologies and didn't ask how our stay was.
When I pay this much for a hotel room, I expect more than the average. It was nice, but not $450/night nice.

We had booked with another hotel this morning and when we arrived our room wouldn’t be ready till 6. Wanted to relax and unpack so called this Springhill Suites and the front desk person could not have been more accommodating! Took my reservation over the phone, when we arrived room was ready and exactly what we wanted! Will definitely stay again! May switch from Hilton to Marriott!
