Dolphin hands down even without construction at CSR. We Love the restaurants, pool is one of the best on property imho, inside corridors, all the perks of onsite except room charging, dining plans and DME. Not to mention walk or boat to two parks and the boardwalk and bcyc restaurants.
Just returned from a short stay at CSR and we were very disappointed. Booked and paid for preferred location, they tried to put us as far away as possible and next to the construction, told us it was a water view upgrade. I had to ask for a manager to get assigned the room category I paid for.
We ended up in a renovated room and it was very nice.
The construction was imho unavoidable - there was construction in the walkways, across the lake and of course the building of the new hi rise. Noise started at 7am every day -
Its going to be really nice when it is done but I would not stay again during construction.
