The Beach & Tennis Resort is a mid-priced (we paid $115 day)
resort on the water on HH island.
I go to HH every year for tennis, & this is one of the better locations, beach wise.
Too, we rented a 2bdrm, near the the bch in 'Admirals Row'
Some units are a bit of a schlep, but we found a nice corner 1st floor unit , that was great w/ our stroller.
The restaurant at the pool is limited, but its nice to have full bar
& kids activities all nearby.
I play tennis at Sea Pines, so I can't comment on the Tennis
at the resort.
The only thing I hear a lot, is that units rented from the resort can be
underwhelming in appearance & cost more than if you go to
one of the 'Rent from Owner' websites. ie VRBO.com

We planned our vacation to HHI because we wanted to spend time outside our hotel room, so when we found HHIB&T for only $111/night, we booked it and held our breath as we turned the key (yes, old-fashioned key-holes!) in the door.

We were pleasantly surprised to find a clean, cozy one-bedroom with two toilets (his and hers!), plenty of closet space, two televisions, DVD player, stovetop, microwave, full fridge, and balcony, among other comforts. The decor left much to be desired: wallpaper cut-outs and felt arts&crafts projects adorned the walls. However, we didn't need fancy-pants amenities to make our vacation.

I loved that it was a couple minutes walk across the boardwalk right onto the beach (no driving, searching for parking, crossing busy roads), and I loved that they had fun kid-friendly activities going on all week. Note: we don't have kids and didn't participate, but the resort appears to really invest in the experience of guests, especially families.

I was so pleased I had to pass the good news to other bound-by-budget travelers!

Just left Hilton Head and HHIB&T....my family went for our last mini vacation before school starts on Aug. 20th. We requested a 3 bedroom w/sleeper sofa, but somehow got a 2 bdrm. It wasn't the best accomodation b/c we had 7 people with us and 3 had to sleep on the floor in the living room...they are young, so, it wasn't too much of a problem. The rooms are small, but we had a renovated room which was very nice. The owners left toys, games and plenty of appliances. We also had internet access.
The grounds were well kept and there are marshy areas, but that's the whole essence of Hilton Head, it's an Island.
Our room (324) was right on the beach (my son, aka The Fish) loooved that and spent most of his time there.
The only downside was some kids, I suppose, committed acts of vandalism on several cars (keyed them) and ours was one targeted.
I will go back to Hilton Head and I would definitely go back to HHIB&T again...after I've tried some other resorts as well.

If you're looking for dirty rooms and rude staff, be sure to stay at Hilton Head Island Beach and Tennis Resort. Upon arrival, our room was absolutely filthy - visible dirt in the bathroom (complete with urine smell) and kitchen, spots on the carpet and bedspread. The staff was less than concerned about our complaints, and only one option was offered: pay more for an "upgraded" room. A request for a refund of my prepayment was met with, "Sorry, you've already signed the contract". The rooms are outdated, the beds are a nightmare, and we didn't want to walk on the carpet barefoot. These would not have been acceptable accomodations for spring breakers at Daytona Beach, much less adults vacationing on Hilton Head Island...
